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 : Epinephrine is an adrenergic agonist primarily used in the management of cardiac arrest, anaphylaxis, and severe asthma attacks. It is not used to reverse the effects of warfarin overdose. Warfarin acts as an anticoagulant by inhibiting vitamin K-dependent clotting factors, and epinephrine has no role in this mechanism.

Choice B reason : Vitamin K is the antidote for warfarin toxicity. Warfarin works by inhibiting the vitamin K-dependent clotting factors II, VII, IX, and X. In the event of an overdose, vitamin K is administered to reverse the anticoagulant effects of warfarin and restore the clotting factor levels to normal. The administration can be oral or intravenous, depending on the severity of the overdose and the urgency of the situation.

Choice C reason : Atropine is an anticholinergic drug used to treat bradycardia (slow heart rate) and as an antidote for organophosphate poisoning. It does not have a role in reversing warfarin overdose as it does not affect the clotting cascade or vitamin K metabolism.

Choice D reason : Protamine is used to reverse the effects of heparin, another anticoagulant, but not warfarin. Protamine sulfate binds to heparin, forming a stable complex and neutralizing its anticoagulant effects. Since warfarin's mechanism of action is different from heparin's, protamine is not effective in reversing warfarin toxicity.

A. Morphine B. Nitroglycerin C. Aspirin D. Oxygen

Correct Answer is D

Explanation

Choice A reason : Morphine is an opioid analgesic used to relieve severe pain and can be administered to patients with myocardial infarction to alleviate chest pain and anxiety. However, it is not the first medication given as it does not address the underlying cause of the myocardial infarction, which is the formation of a blood clot in the coronary arteries.

Choice B reason : Nitroglycerin is a nitrate that helps to dilate blood vessels and improve blood flow. It can be used to relieve chest pain in myocardial infarction, but similar to morphine, it is not the initial medication of choice. The priority is to prevent further blood clotting.

Choice C reason : Administered as soon as possible to inhibit platelet aggregation and reduce clot progression.

Choice D reason : When a myocardial infarction (MI) is suspected, the priority is to address tissue hypoxia and ensure adequate oxygenation to minimize myocardial damage. Administering oxygen helps increase oxygen availability to the ischemic heart tissue, reducing further damage.
