clinical skills questions

Correct Answer: C

Rationale: The correct answer is C because assessing the catheter site for redness and/or swelling is essential in monitoring for signs of infection or complications. Redness and swelling can indicate infection, which requires prompt intervention. A: Applying a sterile gauze dressing is not necessary for a temporary percutaneous dialysis catheter unless specified by the healthcare provider. B: Transparent dressings are typically left in place for several days unless there is a specific reason to change them more frequently. D: Using the catheter for drawing blood samples is not recommended as it can increase the risk of infection and may interfere with the dialysis process.

Correct Answer: C

Rationale: The correct answer is C (80 mL/hour) as it is considered a minimally acceptable urine output for a patient weighing 75 kg. Adequate urine output is crucial for kidney function and fluid balance. The general rule is to maintain a urine output of at least 0.5 mL/kg/hour, which in this case would be 37.5 mL/hour for a 75 kg patient. Option C (80 mL/hour) exceeds this minimum requirement, ensuring proper kidney perfusion and waste elimination. Options A (Less than 30 mL/hour) and D (150 mL/hour) are incorrect as they fall below or exceed the recommended urine output range, potentially indicating renal impairment or fluid overload, respectively. Option B (37 mL/hour) is close to the minimum requirement but does not provide a sufficient margin for variations in fluid status or kidney function.

Correct Answer: B

Rationale: The correct answer is B (80 to 125 mL/min) because this range represents the normal glomerular filtration rate (GFR) for a healthy adult. GFR indicates the rate at which blood is filtered by the kidneys, with 125 mL/min being the average value. Values below 80 mL/min (Choice A) suggest impaired kidney function, while values above 189 mL/min (Choice D) may indicate hyperfiltration or underlying conditions. Choice C (125 to 180 mL/min) falls within the normal range, but the typical average is around 125 mL/min. Thus, choice B is the correct answer as it reflects the standard GFR range for adults.

Correct Answer: D

Rationale: The correct answer is D: syndrome of inappropriate secretion of antidiuretic hormone (SIADH). In this scenario, the patient's symptoms of decreased urine output, shortness of breath, edema, and mental status changes are indicative of fluid overload due to SIADH. SIADH causes excessive release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia. This results in edema, decreased urine output, and neurological symptoms. A: Adrenal crisis presents with hypotension, shock, and electrolyte abnormalities, not consistent with the patient's symptoms. B: Diabetes insipidus would present with excessive urine output and thirst, opposite of the patient's symptoms. C: Myxedema coma results from severe hypothyroidism and presents with hypothermia, bradycardia, and altered mental status, not consistent with the patient's symptoms. In summary, the patient's clinical presentation aligns

Correct Answer: A

Rationale: Rationale for correct answer A: Altered sleep/rest patterns can disrupt insulin regulation, leading to glucose imbalance and predisposing to diabetic ketoacidosis. Lack of sleep affects hormones that regulate blood sugar levels, increasing the risk of DKA. Summary of why other choices are incorrect: B: Eating disorder can affect blood sugar control but is not a direct cause of DKA. C: Exposure to influenza may trigger stress on the body but is not a psychosocial factor contributing to DKA. D: High levels of stress can impact blood sugar levels but are not specific psychosocial factors leading to DKA.
