A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with pneumonia. Which assessment finding requires immediate intervention?

Correct Answer: C

Rationale: The correct answer is C: Use of accessory muscles. In a client with COPD and pneumonia, the use of accessory muscles indicates increased work of breathing and may signal respiratory failure. Immediate intervention is necessary to prevent further deterioration of the respiratory status. Choice A, an oxygen saturation of 90%, though low, may not require immediate intervention as it is above the typical threshold for initiating supplemental oxygen. Choice B, a respiratory rate of 24 breaths per minute, falls within the normal range for an adult and may not be an immediate cause for concern. Choice D, inspiratory crackles, are indicative of fluid in the lungs but may not require immediate intervention unless accompanied by other concerning signs like decreased oxygen saturation or increased respiratory distress.

Correct Answer: C

Rationale: The correct answer is C. A potassium level of 6.5 mEq/L is dangerously high, a condition known as hyperkalemia, and requires immediate intervention to prevent cardiac complications. Hyperkalemia can lead to life-threatening arrhythmias, making it crucial to notify the healthcare provider promptly. Choices A, B, and D do not indicate immediate life-threatening conditions. Elevated serum creatinine levels are expected in CKD, a hemoglobin level of 10 g/dl is within a reasonable range, and a blood glucose level of 150 mg/dl is not acutely concerning in this context.

Correct Answer: B

Rationale: Administering IV fluids as prescribed should be the first intervention for a client with diabetes mellitus admitted with a blood glucose level of 600 mg/dl and unresponsive. This intervention is crucial in managing hyperglycemia by helping to correct dehydration and electrolyte imbalances. Administering 50% dextrose IV push (Choice A) would worsen hyperglycemia in this scenario. Checking the client's blood glucose level (Choice C) is important but not the priority when dealing with an unresponsive client with severe hyperglycemia. Immediate dialysis preparation (Choice D) is not indicated as the first intervention for hyperglycemia.

Correct Answer: D

Rationale: A platelet count of 90,000/mm3 is low and concerning for a client scheduled for a renal biopsy, as it increases the risk of bleeding. Thrombocytopenia, indicated by a low platelet count, can lead to impaired blood clotting, posing a significant risk of bleeding during or after the biopsy procedure. Elevated serum creatinine levels may be expected in chronic kidney disease but are not directly related to bleeding risk during a renal biopsy. Prothrombin time and hemoglobin levels are not as directly relevant to the bleeding risk associated with a renal biopsy as platelet count.

Correct Answer: D

Rationale: The correct answer is D. The statement 'I should reduce my fluid intake to control my blood pressure' indicates a misunderstanding. It is important to note that fluid restriction is not typically necessary when taking calcium channel blockers. Choices A, B, and C demonstrate good understanding of medication adherence, dietary precautions, and nutrition recommendations when taking a calcium channel blocker, making them incorrect choices for further teaching.
