Nursing Elites

1. In a 46-year-old female client admitted for acute renal failure secondary to diabetes and hypertension, which test is the best indicator of adequate glomerular filtration?

• A. Serum creatinine.
• B. Blood urea nitrogen (BUN).
• C. Sedimentation rate.
• D. Urine specific gravity.

Correct answer: A

Rationale: The correct answer is A: Serum creatinine. Creatinine is a product of muscle metabolism that is filtered by the glomerulus. Blood levels of creatinine are not affected by dietary or fluid intake, making it a reliable indicator of kidney function. An elevated creatinine level strongly suggests nephron loss, indicating decreased glomerular filtration rate. Choice B, Blood Urea Nitrogen (BUN), reflects the amount of urea nitrogen in the blood and can be influenced by factors other than kidney function, such as protein intake and liver health, making it less specific for evaluating glomerular filtration. Choice C, Sedimentation rate, is a measure of how quickly red blood cells settle in a test tube and is not a direct marker of kidney function. Choice D, Urine specific gravity, mainly reflects the kidney's ability to concentrate urine and is not a direct indicator of glomerular filtration rate. Therefore, Serum creatinine is the most appropriate test to assess glomerular filtration in this scenario.

2. In a patient with anemia, which of the following is the primary symptom to assess?

• A. Fever.
• B. Chest pain.
• C. Shortness of breath.
• D. Muscle cramps.

Correct answer: C

Rationale: The correct answer is C: Shortness of breath. In a patient with anemia, the primary symptom to assess is shortness of breath. Anemia leads to a reduced oxygen-carrying capacity of the blood, resulting in tissues not receiving adequate oxygen. This can manifest as shortness of breath, especially during physical exertion. Fever (Choice A), chest pain (Choice B), and muscle cramps (Choice D) are not typically primary symptoms of anemia. Fever may suggest an infection, chest pain can be indicative of cardiac issues, and muscle cramps may be related to electrolyte imbalances or neuromuscular disorders.

3. The nurse is caring for several patients who are receiving antibiotics. Which order will the nurse question?

• A. Azithromycin (Zithromax) 500 mg IV in 500 mL of fluid
• B. Azithromycin (Zithromax) 500 mg PO once daily
• C. Erythromycin 300 mg IM QID
• D. Erythromycin 300 mg PO QID

Correct answer: C

Rationale: The nurse should question the order for Erythromycin 300 mg IM QID. Erythromycin and other macrolides should not be given intramuscularly because they cause painful tissue irritation. Options A and B are correct routes for Azithromycin, either intravenously or orally. Option D is a correct route for Erythromycin, which is orally.

4. Upon admission, a 77-year-old female client presents with confusion, loss of appetite, nausea, vomiting, and headache, with a pulse rate of 43 beats per minute. Which question should the nurse prioritize asking the client or her family?

• A. Does the client have her own teeth or dentures?
• B. Does the client take aspirin, and if so, what is the dosage?
• C. Does the client take nitroglycerin?
• D. Does the client take digitalis?

Correct answer: D

Rationale: The correct answer is D. The client's symptoms suggest digitalis toxicity, a potentially life-threatening condition that requires immediate attention. Digitalis toxicity can present with symptoms such as anorexia, nausea, vomiting, headache, and bradycardia (low pulse rate). Given the client's presentation, it is crucial to assess for digitalis use as elderly individuals are more susceptible to this type of intoxication. Choices A, B, and C are important aspects to consider during the assessment, but in this scenario, the priority lies in identifying and addressing the potential digitalis toxicity due to the severity of symptoms and the need for prompt intervention.

5. After pericardiocentesis for cardiac tamponade, for which signs should the nurse assess the client to determine if tamponade is recurring?

• A. Decreasing pulse
• B. Rising blood pressure
• C. Distant muffled heart sounds
• D. Falling central venous pressure (CVP)

Correct answer: C

Rationale: After pericardiocentesis for cardiac tamponade, the nurse should assess for distant muffled heart sounds that were noted before the procedure. If these sounds return, it could indicate recurring pericardial effusion and potential tamponade. Therefore, the correct answer is the return of distant muffled heart sounds (Option C). Decreasing pulse (Option A) and falling central venous pressure (Option D) are not specific signs of recurring tamponade. Rising blood pressure (Option B) is also not a typical sign of tamponade recurrence; in fact, hypotension is more commonly associated with tamponade.
