Nursing Elites

1. The nurse is aware that norepinephrine is secreted by which endocrine gland?

• A. The pancreas
• B. The adrenal cortex
• C. The adrenal medulla
• D. The anterior pituitary gland

Correct answer: C

Rationale: The correct answer is C: The adrenal medulla. Norepinephrine is secreted by the adrenal medulla and is involved in the body's 'fight or flight' response. The pancreas (choice A) secretes insulin and glucagon, not norepinephrine. The adrenal cortex (choice B) secretes hormones like cortisol and aldosterone, but not norepinephrine. The anterior pituitary gland (choice D) secretes various hormones like growth hormone and thyroid-stimulating hormone, but not norepinephrine.

2. During synchronized cardioversion on a client in atrial fibrillation, when the machine is activated, and there is a pause, what action should the nurse take?

• A. Wait until the machine discharges
• B. Shout “all clear” and don’t touch the bed
• C. Make sure the client is all right
• D. Increase the joules and re-discharge

Correct answer: B

Rationale: The correct action for the nurse to take when there is a pause after the machine is activated during synchronized cardioversion is to shout “all clear” and ensure that no one is touching the client or the bed to prevent them from being shocked. This step is crucial for the safety of everyone present during the procedure. Choices A, C, and D are incorrect because waiting without confirming safety, focusing on the client's condition only, or increasing joules without safety precautions can lead to potential harm or injury.

3. The client diagnosed with acute vein thrombosis is receiving a continuous heparin drip, an intravenous anticoagulant. The health care provider orders warfarin (Coumadin), an oral anticoagulant. Which action should the nurse take?

• A. Discontinue the heparin drip prior to initiating the Coumadin
• B. Check the client’s INR prior to beginning Coumadin
• C. Clarify the order with the health care provider as soon as possible
• D. Administer the Coumadin along with the heparin drip as ordered

Correct answer: D

Rationale: The correct action for the nurse to take is to administer the Coumadin along with the heparin drip as ordered. Heparin and warfarin are often given together initially because warfarin takes a few days to become effective. Discontinuing the heparin drip prior to initiating Coumadin could leave the patient without anticoagulation coverage during the period when warfarin's effects are not yet established. Checking the client's INR prior to beginning Coumadin is important but not the immediate action to take when both medications are ordered together. Clarifying the order with the health care provider is unnecessary in this scenario as it is common practice to give heparin and warfarin concurrently in the transition period.

4. A client scheduled for surgery cannot sign the operative consent form because he has been sedated with opioid analgesics. The nurse should take which best action regarding the informed consent?

• A. Obtain a court order for the surgery
• B. Sign the informed consent on behalf of the client
• C. Send the client to surgery without the consent form being signed
• D. Obtain a telephone consent from a family member, with the consent being witnessed by two healthcare providers

Correct answer: D

Rationale: In situations where a client is unable to sign the consent form, obtaining a telephone consent from a family member, with the consent being witnessed by two healthcare providers, is the best course of action. This ensures that the client's best interests are considered and that proper authorization is obtained. Option A, obtaining a court order, is not necessary in this scenario and could delay the surgery. Option B, signing the consent on behalf of the client, is not appropriate as it may raise ethical and legal concerns. Option C, sending the client to surgery without a signed consent form, is not advisable as it violates the principles of informed consent and places the client at risk.

5. A nurse is reviewing the laboratory results for a client with a history of atherosclerosis and notes elevated cholesterol levels. Which statement by the client indicates the nurse should plan follow-up instruction on a low-cholesterol diet?

• A. ''I take an omega-3 supplement daily.''
• B. ''I cook my food with canola oil.''
• C. ''I eat three eggs for breakfast each morning.''
• D. ''I flavor my meat with lemon juice.''

Correct answer: C

Rationale: The correct answer is C. Eating three eggs daily increases cholesterol intake, which could exacerbate atherosclerosis. Omega-3 supplements, cooking with canola oil, and flavoring meat with lemon juice do not significantly impact cholesterol levels compared to consuming three eggs daily. Therefore, the nurse should focus on educating the client to reduce egg consumption to improve cholesterol levels.
