Nursing Elites

1. A client with a UTI and a history of recurrent infections asks why the provider has not yet prescribed an antibiotic. The nurse should explain that the provider has to wait for the results of which of the following laboratory tests to identify which antibiotic to prescribe?

• A. Gram stain
• B. Culture
• C. Sensitivity
• D. Specific gravity

Correct answer: C

Rationale: In the case of a UTI, a sensitivity test is crucial as it identifies the most effective antibiotic to target the specific microorganism causing the infection. This test helps in prescribing the appropriate antibiotic for successful treatment and preventing antibiotic resistance. While a Gram stain and culture are important in diagnosing a UTI, the sensitivity test specifically determines the most suitable antibiotic. Specific gravity, on the other hand, is not related to identifying the appropriate antibiotic for a UTI.

2. A client in the operating room received a dose of Succinylcholine. During the operation, the client suddenly develops rigidity, and their body temperature begins to rise. The healthcare provider should anticipate a prescription for which of the following medications?

• A. Neostigmine
• B. Naloxone
• C. Dantrolene
• D. Vecuronium

Correct answer: C

Rationale: Muscle rigidity and a sudden rise in temperature are manifestations of malignant hyperthermia. Dantrolene acts on skeletal muscles to reduce metabolic activity and treat malignant hyperthermia effectively. Neostigmine (choice A) is used to reverse the effects of non-depolarizing neuromuscular blockers, not to treat malignant hyperthermia. Naloxone (choice B) is an opioid antagonist used for opioid overdose. Vecuronium (choice D) is a non-depolarizing neuromuscular blocker and is not used to treat malignant hyperthermia.

3. During discharge instructions, a client with a new prescription for Phenytoin should be advised to take which of the following actions?

• A. Brush and floss your teeth regularly.
• B. Avoid drinking grapefruit juice.
• C. Take this medication on an empty stomach.
• D. Increase your intake of calcium-rich foods.

Correct answer: A

Rationale: The correct instruction for a client with a new prescription for Phenytoin is to brush and floss their teeth regularly. Phenytoin is known to cause gingival hyperplasia, a condition that affects the gums. By maintaining good oral hygiene practices such as regular brushing and flossing, the client can help minimize the risk of developing this side effect. Choices B, C, and D are incorrect. Avoiding grapefruit juice is more relevant for medications affected by grapefruit juice metabolism, taking medication on an empty stomach is not specifically indicated for Phenytoin, and increasing calcium-rich foods is not directly related to the side effects or administration of Phenytoin.

4. A client has a new prescription for Labetalol. Which of the following instructions should be included?

• A. Take this medication at bedtime.
• B. Avoid sudden discontinuation of the medication.
• C. Increase your intake of sodium-rich foods.
• D. Avoid drinking grapefruit juice.

Correct answer: B

Rationale: The correct answer is to instruct the client to avoid sudden discontinuation of Labetalol. Abrupt discontinuation of beta-blockers like Labetalol can lead to rebound hypertension and other cardiac issues. It is important for clients to taper off the medication under healthcare provider guidance to prevent potential complications.

5. A healthcare professional is caring for a client who is receiving heparin therapy. Which of the following laboratory tests should the healthcare professional monitor to evaluate the therapeutic effect of heparin?

• A. PT/INR
• B. Platelet count
• C. aPTT
• D. WBC count

Correct answer: C

Rationale: The correct test to monitor the therapeutic effect of heparin is the activated partial thromboplastin time (aPTT). Heparin's action is to prolong the clotting time, and aPTT reflects this effect. Monitoring aPTT helps ensure that the client is within the therapeutic range to prevent clot formation while minimizing the risk of bleeding complications. PT/INR is used to monitor warfarin therapy, platelet count assesses for potential thrombocytopenia, and WBC count evaluates for signs of infection or inflammation, not the therapeutic effect of heparin.
