Nursing Elites

1. A client has a new prescription for Brimonidine ophthalmic drops and wears soft contact lenses. Which of the following instructions should the nurse include in the teaching?

• A. This medication can stain your contacts.
• B. This medication can cause your pupils to constrict.
• C. This medication can absorb into your contacts.
• D. This medication can slow your heart rate.

Correct answer: C

Rationale: The correct instruction the nurse should include is that Brimonidine can absorb into soft contact lenses. To prevent this, the client should remove the contacts, instill the medication, and wait at least 15 minutes before putting the contacts back in to avoid any potential absorption of the medication into the lenses. Choices A, B, and D are incorrect because Brimonidine is not known to stain contacts, cause pupil constriction, or slow heart rate.

2. Potassium-sparing diuretics primarily affect which part of the kidney?

• A. Proximal convoluted tubule
• B. Loop of Henle
• C. Collecting duct
• D. Distal convoluted tubule

Correct answer: D

Rationale: Potassium-sparing diuretics exert their primary effects on the distal convoluted tubule in the kidney. By acting on this specific part of the nephron, these diuretics promote sodium excretion while sparing potassium, thus helping to maintain potassium levels in the body. This mechanism differs from other diuretics that may cause potassium loss as a side effect. Understanding the site of action of potassium-sparing diuretics is crucial in clinical practice for managing conditions like hypertension and edema where diuresis is necessary without the risk of hypokalemia.

3. Which of the following is NOT an opioid or NSAID?

• A. Morphine
• B. Ibuprofen
• C. Hydromorphone
• D. Acetaminophen

Correct answer: D

Rationale: Acetaminophen is the correct answer as it is not classified as an opioid or NSAID. Acetaminophen is considered a non-opioid analgesic, which means it works by a different mechanism than opioids and NSAIDs to relieve pain and reduce fever. Morphine, hydromorphone, and ibuprofen, on the other hand, are classified as opioids or NSAIDs. Morphine and hydromorphone are opioids, while ibuprofen is an NSAID (Nonsteroidal Anti-Inflammatory Drug), all of which work through different mechanisms compared to acetaminophen.

4. A healthcare provider is reviewing the health history of a client who has a prescription for Propranolol. Which of the following findings should the provider report?

• A. Previous history of thromboembolism
• B. Concurrent use of an antacid
• C. History of bronchial asthma
• D. Recent weight gain

Correct answer: C

Rationale: Propranolol is a nonselective beta-blocker that can cause bronchoconstriction, making it contraindicated for clients with a history of bronchial asthma. Reporting a history of bronchial asthma to the provider is crucial as it would prompt a review of the medication prescription to avoid potential adverse effects and consider alternative treatment options.

5. Which of the following is not a side effect of Sympathoplegics (Clonidine)?

• A. Hypertension
• B. Difficulty breathing
• C. Dry oral cavity
• D. Lethargic behavior

Correct answer: A

Rationale: The correct answer is A. Clonidine, a Sympathoplegic, typically causes hypotension rather than hypertension. The other side effects associated with Clonidine include dry oral cavity, lethargic behavior, and difficulty breathing, making them incorrect choices in this context.
