NHRA Exam Notes and Study Material for Nurses (2026)

Q1. A patient with congestive heart failure is prescribed furosemide. Which electrolyte imbalance should the nurse monitor for?

1. Hypernatremia
2. HypokalemiaCorrect
3. Hypercalcemia
4. Hypomagnesemia is rare

Explanation: Furosemide is a loop diuretic that causes potassium loss; nurses must monitor for hypokalemia (low potassium).

Q2. Which is the FIRST action when a patient develops anaphylaxis after IV antibiotic administration?

1. Notify the physician
2. Stop the infusionCorrect
3. Administer diphenhydramine
4. Place patient supine

Explanation: Stopping the offending agent (IV antibiotic) is the first nursing action, then assess airway and notify the physician.

Q3. The normal range for adult serum creatinine is:

1. 0.1–0.4 mg/dL
2. 0.6–1.2 mg/dLCorrect
3. 1.5–2.5 mg/dL
4. 3.0–4.0 mg/dL

Explanation: Normal serum creatinine in adults is 0.6–1.2 mg/dL. Elevated values indicate impaired renal function.

Q4. When teaching a diabetic patient about insulin injection sites, the nurse should recommend:

1. Using the same site daily
2. Rotating sites within the same anatomical regionCorrect
3. Avoiding the abdomen
4. Injecting only into muscle

Explanation: Site rotation within one anatomical area (e.g. abdomen) keeps absorption consistent and prevents lipodystrophy.

Q5. A nurse caring for a postpartum patient notes a boggy uterus. The priority nursing action is to:

1. Notify the physician
2. Massage the fundusCorrect
3. Administer oxytocin
4. Encourage ambulation
