1. When providing teaching to a client with a prescription for Hydrochlorothiazide, which instruction should the nurse include?
- A. Take this medication at bedtime.
- B. Avoid foods high in potassium.
- C. Take this medication on an empty stomach.
- D. Monitor for signs of dehydration.
Correct answer: D
Rationale: The correct instruction for a client prescribed Hydrochlorothiazide is to monitor for signs of dehydration. Hydrochlorothiazide is a diuretic that can lead to fluid loss and electrolyte imbalance, potentially causing dehydration. Signs of dehydration include dry mouth, increased thirst, and decreased urine output. Therefore, it is essential for the client to be vigilant in recognizing these symptoms and seek medical attention if they occur. Choices A, B, and C are incorrect. Taking Hydrochlorothiazide at bedtime is not a specific instruction related to its effects or side effects. Avoiding foods high in potassium may be necessary for some medications, but it is not the primary concern with Hydrochlorothiazide. Taking this medication on an empty stomach is not a requirement and may vary depending on individual preferences or healthcare provider instructions.
2. 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.
3. A client with active tuberculosis asks why he must take four different medications. Which of the following responses should the nurse make?
- A. Four medications decrease the risk of a severe allergic reaction.
- B. Four medications reduce the chance that the bacteria will become resistant.
- C. Four medications reduce the risk of adverse reactions.
- D. Four medications decrease the chance of having a positive tuberculin skin test.
Correct answer: B
Rationale: The correct answer is B. When treating tuberculosis, using a combination of medications is crucial to reduce the risk of bacteria developing resistance to any single drug. This approach helps prevent treatment failure and ensures successful treatment outcomes. Choice A is incorrect because the primary purpose of using multiple medications is not related to allergic reactions. Choice C is incorrect as the risk reduction is mainly focused on bacterial resistance rather than adverse reactions. Choice D is not relevant as the purpose of taking multiple medications is not to affect the tuberculin skin test results.
4. A nurse in a clinic is caring for a group of clients. The nurse should contact the provider about a potential contraindication to a medication for which of the following clients? (Select all that apply.)
- A. A client at 8 weeks of gestation who asks for an Influenza immunization
- B. A client who takes Prednisone and has a possible Fungal infection
- C. A client who has chronic liver disease and is taking Hydrocodone
- D. A client who has Peptic Ulcer Disease, takes Sucralfate, and tells the nurse she has started taking OTC Aluminum Hydroxide
Correct answer: B
Rationale: Prednisone, a glucocorticoid, should not be taken by a client who has a possible systemic fungal infection as it can worsen the infection. This combination can suppress the immune response, allowing the fungal infection to proliferate. Therefore, the nurse should contact the provider regarding this potential contraindication to medication. The other options do not present a contraindication related to the medication interactions described in the question.
5. A client has a new prescription for a Nitroglycerin transdermal patch. Which of the following instructions should the nurse include?
- A. Apply the patch to the same site each day.
- B. Remove the patch at night.
- C. Cover the patch with a heating pad.
- D. Apply the patch to a hairless area of skin.
Correct answer: D
Rationale: The correct instruction is to apply the Nitroglycerin transdermal patch to a hairless area of skin. This ensures proper absorption of the medication. It is important to rotate the application site daily to prevent skin irritation and tolerance development. Applying the patch to the same site each day can lead to decreased efficacy and potential skin reactions. Removing the patch at night is not necessary as the patches are usually worn continuously to provide constant medication delivery. Covering the patch with a heating pad can increase the absorption of the medication and lead to an overdose, which is not recommended.
