Nursing Elites

1. A client has the following arterial blood gas (ABG) results: pH 7.51, PCO2 31 mm Hg, PO2 94 mm Hg, HCO3 24 mEq/L. Which of the following acid-base disturbances does the nurse recognize in these results?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: D

Rationale: The ABG results show a pH above the normal range (7.35-7.45) and a decreased PCO2, indicating respiratory alkalosis. In respiratory alkalosis, the pH is increased and the PCO2 is decreased. Metabolic acidosis (choice A) would present with a low pH and low HCO3 levels. Metabolic alkalosis (choice B) would show an increased pH and HCO3 levels. Respiratory acidosis (choice C) would have a low pH and an increased PCO2.

2. A client with heart disease is on a continuous telemetry monitor and has developed sinus bradycardia. In determining the possible cause of the bradycardia, the nurse assesses the client's medication record. Which medication is most likely the cause of the bradycardia?

• A. Propranolol (Inderal).
• B. Captopril (Capoten).
• C. Furosemide (Lasix).
• D. Dobutamine (Dobutrex).

Correct answer: A

Rationale: Propranolol (Inderal) is a beta-adrenergic blocking agent that acts to decrease heart rate and contractility. Sinus bradycardia is a common side effect of beta blockers due to their negative chronotropic effect on the heart. Captopril (Capoten) is an ACE inhibitor used for hypertension and heart failure, not associated with causing bradycardia. Furosemide (Lasix) is a loop diuretic that can lead to electrolyte imbalances but not commonly linked to bradycardia. Dobutamine (Dobutrex) is a beta-1 adrenergic agonist that increases heart rate and contractility, making it an unlikely cause of bradycardia in this scenario.

3. After undergoing a renal biopsy, a client reports pain radiating to the front of the abdomen from the biopsy site. What finding should the nurse assess the client for?

• A. Bleeding
• B. Renal colic
• C. Infection at the site
• D. Increased temperature

Correct answer: A

Rationale: The correct answer is A: Bleeding. Pain radiating to the front of the abdomen from the renal biopsy site suggests bleeding, which should be promptly assessed and managed. Bleeding can lead to serious complications if not addressed timely. Renal colic (choice B) is associated with kidney stones and typically presents with severe flank pain. Infection at the site (choice C) would more likely present with localized signs such as redness, swelling, warmth, and tenderness. Increased temperature (choice D) alone is not specific to the issue described and may be indicative of various conditions.

4. During a paracentesis procedure on a client with abdominal ascites, into which position would the nurse assist the client?

• A. Supine
• B. Upright
• C. Left side-lying
• D. Right side-lying

Correct answer: B

Rationale: During a paracentesis procedure for a client with abdominal ascites, the nurse should assist the client into an upright position. Placing the client upright allows the intestines to float posteriorly, reducing the risk of intestinal laceration during catheter insertion. Choices A, C, and D are incorrect because a supine, left side-lying, or right side-lying position would not provide the same benefit of intestinal mobility and protection during the procedure.

5. A middle-aged adult with a family history of CAD has the following: total cholesterol 198 (11 mmol/L); LDL cholesterol 120 (6.7 mmol/L); HDL cholesterol 58 (3.2 mmol/L); triglycerides 148 (8.2 mmol/L); blood sugar 102 (5.7 mmol/L); and C-reactive protein (CRP) 4.2. The health care provider prescribes a statin medication and aspirin. The client asks the nurse why these medications are needed. Which is the best response by the nurse?

• A. The labs indicate severe hyperlipidemia and the medications will lower your LDL, along with a low-fat diet.
• B. The triglycerides are elevated and will not return to normal without these medications.
• C. The CRP is elevated indicating inflammation seen in cardiovascular disease, which can be lowered by the medications prescribed.
• D. These medications will reduce the risk of type 2 diabetes.

Correct answer: C

Rationale: CRP is a marker of inflammation, which is elevated in cardiovascular disease. Statins and aspirin help lower CRP and reduce the risk of heart attacks and strokes.
