Question 1

A patient with multiple vitamin deficiencies is prescribed oral vitamin C as part of a vitamin supplementation treatment. Which of the following instructions regarding vitamin C should be given to this patient?

Accepted Answer

Vitamin C is a water-soluble vitamin that can be easily destroyed by heat and light. Therefore, it is important to keep the tablets away from sources of heat and light. Option B is incorrect because it is not necessary to only take vitamin C when you are unable to eat citrus fruits. Option C is incorrect because vitamin C can interact with certain medications, such as blood thinners. Option D is incorrect because vitamin C is a water-soluble vitamin and is not primarily used to treat blood clotting disorders.

Question 2

A patient informs you that she is buying over-the-counter (OTC) drugs online from another country because they are cheaper. What is your best response?

Accepted Answer

Buying OTC drugs online from another country can be risky as the drugs may be counterfeit or dangerous. It is important to advise the patient to purchase OTC drugs from a reputable local pharmacy.

Question 3

During your assessment of a clinic patient, the patient asks you if using expired over-the-counter (OTC) drugs would cause harm. What is your best answer?

Accepted Answer

It is important to safely dispose of expired drugs, including over-the-counter drugs, as their effectiveness and safety cannot be guaranteed after the expiration date. Using expired drugs could lead to adverse effects and potential harm.

Question 4

You are teaching a patient with a dietary deficiency of riboflavin about foods that contain riboflavin that should be part of the patient's diet. Which of the following foods would be recommended?

Accepted Answer

Dairy products are a good source of riboflavin, which is important for patients with a riboflavin deficiency.

Question 5

Which patient would be most likely to develop a vitamin B₁₂ deficiency?

Accepted Answer

Vitamin B12 is primarily found in animal products, so individuals who follow a strict vegetarian or vegan diet may be at risk for a deficiency.

Question 6

A patient with a severe upper respiratory infection tells you she is taking mega-doses of vitamin C to help her get rid of the infection quicker. What is your best response?

Accepted Answer

While vitamin C is essential for immune function, taking mega-doses of vitamin C is not effective for treating upper respiratory infections. Vitamin C is water-soluble, meaning that excess amounts are excreted very quickly from the body, making it difficult for the body to absorb and utilize high doses. Therefore, it is not recommended to take mega-doses of vitamin C for treating infections.

Question 7

Which drug category is associated with pyridoxine deficiency?

Accepted Answer

Oral contraceptives are associated with decreased levels of vitamin B6 (pyridoxine) in the body, leading to a potential deficiency.

Question 8

You are evaluating a patient's understanding of a newly prescribed drug regimen for the prevention of heart disease. Which response made by the patient demonstrates understanding of the drug regimen?

Accepted Answer

The correct response is C because it states the specific drug regimen that was prescribed. Taking folic acid every other day (A) is not the complete prescription and taking calcium supplements (B) and a multivitamin with ferrous sulfate (D) are not part of the heart disease prevention regimen.

Question 9

You are caring for a patient who has a family history of cancer. The patient reports taking vitamin E daily for cancer prevention. What is your best response?

Accepted Answer

According to current research, there is no evidence to support the claim that taking vitamin E can prevent cancer. It is important to rely on evidence-based recommendations and not solely on personal beliefs or family history when it comes to cancer prevention.

Question 11

Which statement about multivitamins is true?

Accepted Answer

While some people may use multivitamins under the guidance of a healthcare professional, many do not and may not be aware of potential interactions or side effects.

Answer: D
 This statement is false. Multivitamins can pose a risk for adverse effects, especially if taken in high doses or with certain medications. It is important to consult with a healthcare professional before starting any new supplement regimen.

Question 12

A patient has been admitted for suspected vitamin A overdose. What symptoms would you expect the patient to exhibit?

Accepted Answer

Vitamin A overdose, also known as hypervitaminosis A, can lead to yellowing of the skin, particularly in areas with high concentrations of sebaceous glands like the nose and ears, due to the accumulation of carotenoids. This symptom is distinct from jaundice, which affects the whites of the eyes and is related to liver function.

Question 13

A newly pregnant woman placed on folic acid states she does not want to take any drugs during her pregnancy. What is your best response?

Accepted Answer

Folic acid is given to prevent neural tube defects of the spinal cord. It is important for pregnant women to take folic acid supplements because it helps form the neural tube, which develops into the baby's brain and spinal cord. Neural tube defects can occur during the first few weeks of pregnancy, which is often before many women even know they are pregnant. Therefore, it is important to take folic acid supplements before becoming pregnant and during the first few weeks of pregnancy to ensure the best chance of preventing neural tube defects.

Question 14

What information is important to include when teaching parents about giving over-the-counter (OTC) drugs to children?

Accepted Answer

Question 15

You are teaching a patient about taking over-the-counter (OTC) drugs. Which important safety information should you include in your teaching plan?

Accepted Answer

It is important for patients to understand that OTC drugs can interact with other medications, as well as food and alcohol, which can affect their effectiveness and potentially cause harm. It is also important for patients to consult their healthcare provider before taking any new medications, especially if they are already taking prescription medications. A, C, and D are not correct because they can lead to misuse or mishandling of OTC drugs. It is important to follow expiration dates, take the prescribed amount, and not adjust the dosage without consulting a healthcare provider.

Question 16

A patient you are caring for has been started on niacin as part of a regimen to reduce hyperlipidemia. Which unpleasant side effects of niacin should you teach this patient to expect?

Accepted Answer

Niacin is known to cause skin warmth and flushing, especially on the face and neck, as a result of histamine release. Yellow-tinged skin and sclera (jaundice) and beefy-red tongue are not side effects of niacin. Watery eyes are also not a common side effect of niacin.

Question 17

A patient with depression tells you she is using St. John's wort to treat her symptoms because she would rather use a natural product, as she already takes many prescription drugs. What is your best response?

Accepted Answer

St. John's wort has been shown to interact with many prescription drugs, reducing their effectiveness or causing dangerous side effects. Therefore, it is important to advise the patient to avoid taking St. John's wort if she is taking any prescription drugs.

Question 18

Which of the following drug types is not regulated by the Food and Drug Administration?

Accepted Answer

Herbal supplements are not strictly regulated by the FDA in the same way that prescription drugs and even over-the-counter medications are. While the FDA does have some oversight over herbal supplements, they are not subject to the same rigorous testing and regulation as other types of drugs.

Question 19

A newly pregnant patient is taking oral vitamin A to encourage embryo growth. What would you include in your teaching plan for this patient?

Accepted Answer

It is important to inform the patient that high doses of vitamin A can cause birth defects and therefore, they should only take the amount prescribed by their healthcare provider. It is also important to note that vitamin A is a fat-soluble vitamin, not a water-soluble vitamin. Taking vitamin A during the first 12 weeks of pregnancy is not recommended as it can increase the risk of birth defects. Similarly, taking vitamin A in the last trimester of pregnancy does not encourage fetal growth and can still cause harm to the fetus.

Question 20

A patient in the clinic asks you if she should purchase an expensive brand-name multivitamin because cheaper vitamins may not be as good. What is your best response to this patient?

Accepted Answer

The cost of the vitamin preparation is not always an indication of its effectiveness. Cheaper vitamins can provide the same benefits as expensive ones. It is important to look for a reputable brand that has been tested and ensures the quality and potency of its products.
