1. Which of the following drugs is associated with extreme photosensitivity as a reaction?

A. Digitalis
B. Niacin
C. Tetracycline
D. Fluoroquinolones

Correct answer: C

Rationale: Tetracycline is known to cause extreme photosensitivity reactions, making individuals more sensitive to sunlight and increasing the risk of severe sunburn. It is essential for patients taking tetracycline to protect themselves from excessive sun exposure to prevent adverse reactions.

2. What is the therapeutic use of metformin?

A. Lower blood pressure
B. Diminish seizure activity
C. The maintenance of a person's blood glucose levels
D. Increase heart rate and decrease gastrointestinal secretions

Correct answer: C

Rationale: Metformin is commonly prescribed to manage and control blood glucose levels in individuals with diabetes. It helps in reducing the amount of glucose produced by the liver and improves the body's response to insulin, thereby aiding in the regulation of blood sugar levels. It is not used to lower blood pressure, diminish seizure activity, increase heart rate, or decrease gastrointestinal secretions.

3. A client is being educated about Fluticasone for treating Perennial Rhinitis. Which statement by the client indicates an understanding of the teaching?

A. I should use the spray every 4 hours while I am awake.
B. It can take as long as 3 weeks before the medication takes maximum effect.
C. This medication can also be used to treat motion sickness.
D. I can use this medication when my nasal passages are blocked.

Correct answer: B

Rationale: Correct! While the client may experience some benefits of Fluticasone within a few hours, the maximum effects may not be seen until up to 3 weeks of consistent use. This understanding is important to manage expectations and ensure the client uses the medication effectively for the treatment of Perennial Rhinitis.

4. A patient is prescribed acetaminophen 650 mg PO every 6 hr PRN for pain. The available acetaminophen liquid is 500 mg/5 mL. How many mL should the nurse administer per dose?

A. 6.5 mL
B. 7 mL
C. 5 mL
D. 8 mL

Correct answer: A

Rationale: To calculate the volume to administer: (Desired dose / Concentration) = Volume to administer. In this case, (650 mg / 500 mg) x 5 mL = 6.5 mL. Therefore, the nurse should administer 6.5 mL of acetaminophen liquid per dose to provide the prescribed 650 mg of acetaminophen. Choice B, 7 mL, is incorrect because the correct calculation results in 6.5 mL. Choice C, 5 mL, is incorrect as it is the concentration of the acetaminophen liquid, not the final volume needed. Choice D, 8 mL, is incorrect because it does not reflect the accurate calculation based on the prescription and concentration.

5. What is a severe adverse effect of iron supplementation?

A. Seizures
B. Dry mouth
C. Edema
D. Serotonin syndrome

Correct answer: A

Rationale: A severe adverse effect of iron supplementation is seizures. Iron toxicity can lead to symptoms such as abdominal pain, vomiting, bloody diarrhea, lethargy, and in severe cases, seizures. It is important for individuals taking iron supplements to follow recommended dosages to prevent adverse effects.
