1. Which lab result would be most indicative of renal failure?

Correct answer: A

Rationale: The correct answer is A: Elevated creatinine levels. Creatinine is a waste product that is normally filtered by the kidneys. Elevated creatinine levels indicate impaired kidney function, which is commonly seen in renal failure. Choice B, low potassium levels, is not typically associated with renal failure. In fact, renal failure is more likely to cause high potassium levels due to the kidneys' inability to excrete potassium effectively. Choice C, low calcium levels, are not directly indicative of renal failure. Renal failure can lead to disturbances in calcium levels, but low calcium levels alone are not a specific marker for renal failure. Choice D, high sodium levels, are also not typically associated with renal failure. In renal failure, there may be disturbances in sodium levels, but high sodium levels alone are not a direct indicator of renal failure.

2. A client is placed on fluid restrictions because of chronic kidney disease (CKD). Which assessment finding would alert the nurse that the client’s fluid balance is stable at this time?

Correct answer: C

Rationale: The absence of adventitious sounds upon auscultation of the lungs is a key indicator that the client's fluid balance is stable. Adventitious sounds, such as crackles or wheezes, are typically heard in conditions of fluid overload, indicating that the body is retaining excess fluid. Choices A and B, decreased calcium levels and increased phosphorus levels, are common laboratory findings associated with chronic kidney disease (CKD) and are not directly related to fluid balance. Increased edema in the legs is a sign of fluid imbalance, suggesting fluid retention in the tissues, which would not indicate stable fluid balance in a client with CKD on fluid restrictions.

3. 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?

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.

4. A pregnant client tells the nurse, “I am experiencing a burning pain when I urinate.” How should the nurse respond?

Correct answer: C

Rationale: Pregnant clients with a urinary tract infection require prompt and aggressive treatment because cystitis can lead to acute pyelonephritis during pregnancy. The nurse should encourage the client to make an appointment and have the infection treated. Burning pain when urinating does not indicate the start of labor or weakening of pelvic muscles. Choice A is incorrect because burning pain during urination does not signify the start of labor. Choice B is incorrect because while cranberry juice may help prevent urinary tract infections, it is not a treatment. Choice D is incorrect because burning pain when urinating is not indicative of weakening pelvic muscles.

5. A client is undergoing hemodialysis. The client’s blood pressure at the beginning of the procedure was 136/88 mm Hg, and now it is 110/54 mm Hg. What actions should the nurse perform to maintain blood pressure? (Select all that apply.)

Correct answer: D

Rationale: During hemodialysis, a drop in blood pressure can occur due to fluid removal. To maintain blood pressure, the nurse should consider adjusting the rate of extracorporeal blood flow to optimize fluid removal without causing hypotension. Placing the client in the Trendelenburg position can help improve venous return and cardiac output. Administering a bolus of normal saline can help increase intravascular volume and support blood pressure. Therefore, all the actions listed in choices A, B, and C are appropriate measures to maintain blood pressure during hemodialysis. Choice D, 'All of the above,' is the correct answer as it encompasses all the relevant actions to address the dropping blood pressure effectively. Choices A, B, and C, when implemented together, can help manage hypotension during hemodialysis.
