1. A client has a prescription for Trimethoprim-Sulfamethoxazole. Which of the following instructions should the nurse include?
- A. Take the medication with food.
- B. Increase fluid intake.
- C. Expect reddish-orange urine.
- D. Avoid high-protein foods.
Correct answer: B
Rationale: The correct instruction for a client prescribed Trimethoprim-Sulfamethoxazole is to increase fluid intake. This helps prevent crystalluria and kidney stones, which are potential adverse effects of this medication. Adequate hydration is essential to reduce the risk of these complications.
2. A healthcare professional is preparing to administer clindamycin 200 mg by intermittent IV bolus. The amount available is clindamycin injection 200 mg in 100 mL 0.9% sodium chloride (0.9% NaCl) to infuse over 30 min. The healthcare professional should set the IV pump to deliver how many mL/hr?
- A. 200 mL/hr
- B. 150 mL/hr
- C. 100 mL/hr
- D. 250 mL/hr
Correct answer: A
Rationale: To calculate the flow rate in mL/hr: (Volume in mL / Time in hours) = Flow rate in mL/hr. In this case, (100 mL / 0.5 hr) = 200 mL/hr. The correct calculation is: 100 mL (volume) / 0.5 hr (time) = 200 mL/hr. Therefore, the correct answer is 200 mL/hr. Choice B (150 mL/hr), C (100 mL/hr), and D (250 mL/hr) are incorrect as they do not match the calculated flow rate needed for the administration of clindamycin.
3. A client has Diabetes Mellitus, Pulmonary Tuberculosis, and a new prescription for Isoniazid. Which of the following supplements should the nurse expect to administer to prevent an adverse effect of INH?
- A. Ascorbic acid
- B. Pyridoxine
- C. Folic acid
- D. Cyanocobalamin
Correct answer: B
Rationale: Pyridoxine is administered with Isoniazid to prevent peripheral neuropathy, a common adverse effect of the drug. It is essential to provide this supplement to the client to minimize the risk of developing this adverse effect. Ascorbic acid (Vitamin C) is not typically given to prevent INH adverse effects. Folic acid and Cyanocobalamin are not commonly administered with INH for this purpose.
4. While caring for a client receiving epoetin alfa to treat anemia, which finding should the nurse monitor for?
- A. Leukocytosis
- B. Hypertension
- C. Hyperkalemia
- D. Fever
Correct answer: B
Rationale: The nurse should monitor the client for hypertension when receiving epoetin alfa. Epoetin alfa stimulates red blood cell production, which can lead to increased blood pressure. Leukocytosis (increased white blood cells) and hyperkalemia (high potassium levels) are not typically associated with epoetin alfa therapy. Fever is also not a common adverse effect of this medication.
5. When administering medications to a 4-month-old infant, which of the following pharmacokinetic principles should be considered? (Select all that apply.)
- A. Infants have a more rapid gastric emptying time.
- B. Infants have immature liver function.
- C. Infants' blood-brain barrier is poorly developed.
- D. Infants have an increased ability to absorb topical medications.
Correct answer: B
Rationale: When administering medications to a 4-month-old infant, the pharmacokinetic principle to consider is that infants have immature liver function until 1 year of age. This requires medications metabolized by the liver to be administered in smaller dosages. While infants do have a more rapid gastric emptying time, immature liver function is a more critical pharmacokinetic consideration in this context. Additionally, although infants have a poorly developed blood-brain barrier, this relates more to pharmacodynamic effects rather than pharmacokinetic principles. The statement about infants having an increased ability to absorb topical medications is not directly related to pharmacokinetic principles, making choice B the correct answer.
