Nursing Clinical Skills questions

Correct Answer: C

Rationale: The correct answer is C: dialysis disequilibrium syndrome. This syndrome occurs when there is a rapid shift in electrolytes, especially in the brain, due to the removal of waste products during hemodialysis. The symptoms of headache, nausea, and confusion align with this syndrome as the brain struggles to adjust to the changes. Dialyzer membrane incompatibility (A) is unlikely as it typically presents with allergic reactions, not neurological symptoms. A shift in potassium levels (B) may cause symptoms like muscle weakness or irregular heartbeat, not headache and confusion. Hypothermia (D) would present with low body temperature, shivering, and confusion, but in this case, the symptoms are more indicative of dialysis disequilibrium syndrome.

Correct Answer: A

Rationale: The correct answer is A: Heredity. Nephrogenic diabetes insipidus can be inherited as a genetic condition. The mutation in genes responsible for regulating water balance in the kidneys can lead to this disorder. Other choices are incorrect: B: Medications like lithium can cause acquired nephrogenic diabetes insipidus, not its development. C: Meningitis is an inflammatory condition that does not directly relate to nephrogenic diabetes insipidus. D: Pituitary tumors are associated with central diabetes insipidus, not nephrogenic.

Correct Answer: D

Rationale: The correct answer is D: �Recovery is possible, but it may take several months.� This response is the best because acute kidney injury can be reversible with appropriate management, and recovery may take time. It is important to provide hope and encouragement to the patient. A: �Unfortunately, kidney injury is not reversible; it is permanent.� - This is incorrect as acute kidney injury can be reversible with timely intervention and proper treatment. B: �Kidney function usually returns within 2 weeks.� - This is incorrect because the recovery timeline varies for each individual and can take longer than 2 weeks. C: �You will know for sure if you start urinating a lot all at once.� - This is incorrect as increased urine output may not always indicate complete recovery from acute kidney injury.

Correct Answer: C

Rationale: The correct answer is C (10 to 20 mg/dL). In conditions where the serum creatinine level is elevated (7 mg/dL in this case), the BUN level is expected to also be elevated due to impaired kidney function. BUN levels are typically around 10-20 mg/dL, so this range is the most appropriate given the elevated creatinine level. Choice A (1 to 2 mg/dL) is too low and would not be expected with a creatinine level of 7 mg/dL. Choice B (7 to 14 mg/dL) is a bit low for such a high creatinine level. Choice D (20 to 30 mg/dL) is too high as it exceeds the typical range for BUN levels. Therefore, choice C is the most appropriate range based on the given information.

Correct Answer: D

Rationale: The correct answer is D. Auscultating the left arm for a bruit and palpating for a thrill post arteriovenous fistula implantation is crucial to assess the patency and functionality of the fistula. A bruit indicates turbulent blood flow, while a thrill signifies the presence of a strong pulse through the fistula. These assessments help identify any complications like stenosis or thrombosis. Drawing blood or taking blood pressures from the arm with the fistula can lead to inaccurate results or damage the fistula. Starting a new IV line in the left lower arm is unnecessary and not relevant to monitoring the arteriovenous fistula.
