A nurse is reviewing the laboratory results for a male adult client who is at risk for peripheral arterial disease due to atherosclerosis. The nurse should identify which of the following results places the client at risk :

Triglycerides : 130 mg/dL

HDL : 84 mg/dL

Blood glucose : 92 mg/dL

LDL : 172 mg/dL

Answer and Explanation

The Correct Answer is D

Choice A reason : The triglyceride level of 130 mg/dL is within the normal range, which is less than 150 mg/dL for adults. Therefore, this result does not place the client at risk for peripheral arterial disease.

Choice B reason : An HDL level of 84 mg/dL is considered good as it is higher than the minimum recommended level of 40 mg/dL for males and 50 mg/dL for females. Higher levels of HDL are protective against heart disease.

Choice C reason : A blood glucose level of 92 mg/dL is within the normal fasting range of 70 to 99 mg/dL. This indicates that the client does not have diabetes, which is a risk factor for peripheral arterial disease.

Choice D reason : An LDL level of 172 mg/dL is considered high since the optimal level for LDL is less than 100 mg/dL. High levels of LDL cholesterol can lead to atherosclerosis, increasing the risk for peripheral arterial disease.

Correct Answer is B

Explanation

Choice A reason : An erythrocyte sedimentation rate (ESR) test is not directly related to high serum potassium levels and would not be the immediate action in response to hyperkalemia.

Choice B reason : Obtaining a 12-lead ECG is a critical step when hyperkalemia is suspected because high potassium levels can cause life-threatening cardiac arrhythmias. An ECG can quickly reveal characteristic changes associated with hyperkalemia, allowing for prompt treatment.

Choice C reason : Administering potassium gluconate would be contraindicated in a patient with hyperkalemia, as it would further increase the serum potassium levels, potentially leading to severe complications.

Choice D reason : Restricting fluid intake is not a standard treatment for hyperkalemia. The management of hyperkalemia may include medications or procedures that promote the excretion of potassium or move potassium from the blood into the cells.

A. Hemoglobin (Hgb) : 16 g/dL B. Prothrombin Time (PT) : 45 seconds C. Activated Partial Thromboplastin Time (aPTT) : 36 seconds D. Platelets : 190,000/mm

Correct Answer is B

Explanation

Choice A reason : A hemoglobin (Hgb) level of 16 g/dL is within the normal range for adults, which typically falls between 13.8 to 17.2 g/dL for men and 12.1 to 15.1 g/dL for women. Therefore, this value does not warrant reporting to the provider as it does not indicate an immediate concern.

Choice B reason : A prothrombin time (PT) of 45 seconds is significantly higher than the normal range of 11 to 13.5 seconds for individuals not on anticoagulation therapy. For patients on warfarin, the target PT is usually 1.5 to 2 times the normal value, depending on the indication for therapy. However, a PT of 45 seconds suggests a high risk of bleeding and requires immediate medical attention.

Choice C reason : The activated partial thromboplastin time (aPTT) of 36 seconds is within the normal range of approximately 21 to 35 seconds⁸. This result indicates that the blood's intrinsic clotting pathway is functioning within expected parameters and does not need to be reported.

Choice D reason : A platelet count of 190,000/mm is within the normal range, which is typically 150,000 to 450,000 platelets/mm. This value is not concerning and does not need to be reported to the provider.
