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 hospitalized client receiving IV heparin for a deep-vein thrombosis begins vomiting blood. After the heparin has been stopped, which of the following medications should the nurse prepare to administer?

• A. Vitamin K1
• B. Atropine
• C. Protamine
• D. Calcium gluconate

Correct answer: C

Rationale: In this scenario, the client is experiencing a serious complication of heparin therapy, likely due to heparin-induced thrombocytopenia. Protamine is the antidote for heparin and can reverse its anticoagulant effects. It is essential to administer protamine promptly to counteract the effects of heparin and manage the bleeding. Vitamin K1 is used to reverse the effects of warfarin, not heparin. Atropine is used to treat bradycardia or some types of poisoning. Calcium gluconate is used to manage hyperkalemia or calcium channel blocker toxicity, not to reverse heparin's effects.

3. Which of the following drugs has a therapeutic effect that prevents thromboembolic events?

• A. Warfarin
• B. Amlodipine
• C. Nitroglycerin
• D. Clopidogrel

Correct answer: A

Rationale: The correct answer is Warfarin. Warfarin is an anticoagulant medication that helps prevent thromboembolic events by inhibiting the formation of blood clots. It is commonly used to reduce the risk of strokes or heart attacks in patients at risk for thrombosis.

4. A client is prescribed gentamicin for an infection. Which finding indicates a potential adverse reaction to the medication?

• A. Blood pressure 160/90 mm Hg
• B. Presence of red blood cells in the urine
• C. Urine output of 35 mL/hr
• D. Respiratory rate of 22/min

Correct answer: B

Rationale: The presence of red blood cells in the urine is a significant finding that can indicate nephrotoxicity, a potential adverse effect of gentamicin. Nephrotoxicity can lead to kidney damage, and monitoring for this adverse reaction is crucial during gentamicin therapy. Elevated blood pressure (Choice A) is not typically associated with gentamicin adverse reactions. Decreased urine output (Choice C) may suggest kidney impairment but is not as specific as the presence of red blood cells in the urine. Respiratory rate (Choice D) is not directly related to potential adverse reactions to gentamicin.

5. When administering subcutaneous enoxaparin 40 mg using a prefilled syringe of Enoxaparin 40 mg/0.4 mL to an adult client following hip arthroplasty, what action should the nurse plan to take?

• A. Expel any air bubbles from the prefilled syringe before injecting.
• B. Insert the needle completely into the client's tissue.
• C. Administer the injection in the client's thigh.
• D. Aspirate carefully after inserting the needle into the client's skin.

Correct answer: B

Rationale: When administering enoxaparin via a prefilled syringe for deep subcutaneous injection, the nurse should insert the needle completely into the client's tissue. This action ensures proper delivery of the medication into the subcutaneous layer, promoting optimal therapeutic effects. Choice A is incorrect because there is no need to expel air bubbles from a prefilled syringe. Choice C is incorrect as enoxaparin is typically administered in the abdomen for subcutaneous injections. Choice D is incorrect as aspiration is not recommended for subcutaneous injections to avoid trauma or damage to tissues.
