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: A

Rationale: The presence of protein in the glomerular filtrate indicates a problem with renal function as healthy kidneys should not allow large molecules like proteins to pass through the filtration barrier. This could be a sign of kidney damage or dysfunction. Sodium, creatinine, and red blood cells are normally present in the filtrate and are not specific indicators of renal function issues. Sodium is actively reabsorbed in the renal tubules, creatinine is a waste product filtered by the kidneys, and a small number of red blood cells may pass through the filtration barrier under normal circumstances.

Correct Answer: C

Rationale: The correct answer is C: �The fistula will be usable in about 4 to 6 weeks.� This is because arteriovenous fistulas typically require a maturation period of 4 to 6 weeks before they can be used for dialysis. During this time, the fistula will develop into a strong, durable access point for hemodialysis. Choice A is incorrect because the fistula needs time to mature before it can be used, and immediate use may damage it. Choice B is incorrect as it underestimates the maturation period required. Choice D is incorrect as the maturation time does not depend on the manufacturer but on the patient's physiology and healing process.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Administering levothyroxine is crucial in treating myxedema coma as it helps replace the deficient thyroid hormone. 2. This intervention addresses the underlying cause of myxedema coma, which is severe hypothyroidism. 3. Levothyroxine administration can help reverse the symptoms of myxedema coma and improve the patient's condition. Summary of Incorrect Choices: - B: Encouraging high sodium intake is not appropriate as myxedema coma is associated with fluid retention and sodium may exacerbate this. - C: Passive rewarming interventions are not relevant for myxedema coma, as the condition is not typically related to hypothermia. - D: While monitoring airway and respiratory effort is important in general patient care, it is not a specific intervention for myxedema coma.

Correct Answer: A

Rationale: Explanation: A: Acidosis is a common reason to initiate dialysis in acute kidney injury due to impaired acid-base balance. B: Hypokalemia is not a common reason for initiating dialysis in acute kidney injury. C: Volume overload may require dialysis but is not as common as acidosis. D: Hyperkalemia is a valid reason for dialysis but not as common as acidosis in acute kidney injury.
