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. Which dietary change is most beneficial for a patient with hypertension?

• A. Increased sodium intake
• B. Decreased potassium intake
• C. Increased fiber intake
• D. Increased cholesterol intake

Correct answer: C

Rationale: The correct answer is C: Increased fiber intake. A diet high in fiber is beneficial for patients with hypertension as it helps lower blood pressure. Increased sodium intake (choice A) is not recommended as it can raise blood pressure. Decreasing potassium intake (choice B) is not advisable as potassium helps regulate blood pressure. Increased cholesterol intake (choice D) is also not recommended as high cholesterol levels can contribute to cardiovascular issues, including hypertension.

3. When palpating the client's neck for lymphadenopathy, where should the nurse position himself?

• A. At the client's back
• B. At the client's right side
• C. At the client's left side
• D. In front of a sitting client

Correct answer: D

Rationale: When palpating the client's neck for lymphadenopathy, the nurse should position himself in front of a sitting client. This positioning allows for easier access to the neck area and better visualization of any swelling or abnormalities in the lymph nodes. Being in front of the client ensures proper alignment and comfort for both the nurse and the client during the assessment. Choices A, B, and C are incorrect because positioning at the client's back or sides would make it challenging to adequately palpate the neck area and assess for lymphadenopathy.

4. What is established when threats to air resources prevent evacuation by air from forward units?

• A. Area support medical battalions
• B. TOE units
• C. Ambulance exchange points
• D. Field hospitals

Correct answer: C

Rationale: Ambulance exchange points are established when threats to air resources prevent evacuation by air from forward units. These points serve as locations where patients can be transferred between ground and air ambulances. Area support medical battalions (Choice A) refer to medical units that provide medical support to large areas and are not specifically related to evacuation. TOE units (Choice B) and field hospitals (Choice D) are not typically established in response to threats to air resources affecting evacuation.

5. The nurse is analyzing laboratory values for the assigned clients. Which finding, based on the client's medical history, indicates the need for immediate follow-up?

• A. Client with chronic kidney disease and serum creatinine of 1.6 mg/dL
• B. Client with diabetes mellitus and a glycosylated hemoglobin A (HbA1c) of 7.0%
• C. Client with heart failure and a B-type natriuretic peptide (BNP) of 140 pg/mL
• D. Client who is male and has anemia with hemoglobin of 16.5 g/dL and hematocrit of 45%

Correct answer: B

Rationale: An HbA1c of 7.0% in a client with diabetes mellitus indicates poor long-term glucose control, necessitating immediate follow-up. Elevated HbA1c levels suggest a higher average blood sugar over the past 2-3 months, increasing the risk of complications associated with diabetes. Choices A, C, and D do not require immediate follow-up based solely on the provided information. A serum creatinine of 1.6 mg/dL in a client with chronic kidney disease, a BNP of 140 pg/mL in a client with heart failure, and hemoglobin of 16.5 g/dL and hematocrit of 45% in a male client with anemia are within acceptable ranges or do not indicate an urgent need for intervention.
