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 admitted from a nursing home after several recent falls needs a urine sample for culture and sensitivity. What should the nurse complete first?

• A. Obtain urine sample for culture and sensitivity.
• B. Administer intravenous antibiotics.
• C. Encourage protein intake and additional fluids.
• D. Consult physical therapy for gait training.

Correct answer: A

Rationale: In this scenario, the priority intervention is to obtain a urine sample for culture and sensitivity. Older adults with recent falls may have atypical symptoms of urinary tract infection (UTI), which can present as new-onset confusion or falling. It is crucial to rule out UTI before initiating antibiotics. While administering antibiotics, encouraging protein intake, fluids, and consulting physical therapy are important interventions, they should follow the urine sample collection to ensure accurate diagnosis and appropriate treatment.

3. A client with chronic renal failure is being treated with sodium polystyrene sulfonate (Kayexalate). The nurse should monitor the client for which of the following?

• A. Hyponatremia.
• B. Hypokalemia.
• C. Hyperkalemia.
• D. Hypocalcemia.

Correct answer: C

Rationale: The correct answer is C: Hyperkalemia. Sodium polystyrene sulfonate (Kayexalate) is used to treat high potassium levels (hyperkalemia) by exchanging sodium ions for potassium ions in the large intestine, which is then eliminated through the feces. Therefore, the nurse should monitor the client for changes in potassium levels to ensure the effectiveness of the treatment. Choices A, B, and D are incorrect because sodium polystyrene sulfonate (Kayexalate) is not associated with causing hyponatremia, hypokalemia, or hypocalcemia.

4. The patient will begin taking penicillin G procaine (Wycillin). The nurse notes that the solution is milky in color. What action will the nurse take?

• A. Call the pharmacist and report the milky color.
• B. Add normal saline to dilute the medication.
• C. Call the physician and report the milky appearance.
• D. Administer the medication as ordered by the physician.

Correct answer: D

Rationale: The correct answer is to administer the medication as ordered by the physician. Penicillin G procaine (Wycillin) is known to have a milky appearance, which is normal. The milky color should not raise concerns for the nurse as it is an expected characteristic of this medication. Calling the pharmacist (choice A) or the physician (choice C) unnecessarily would delay the administration of the medication. Adding normal saline to dilute the medication (choice B) is not appropriate and could alter the medication's effectiveness. Therefore, the nurse should proceed with administering the medication as prescribed without any further action based on its milky appearance.

5. The client is being educated by the nurse on home blood glucose monitoring. Which of the following blood glucose measurements indicates hypoglycemia?

• A. 59 mg/dL (3.3 mmol/L)
• B. 75 mg/dL (4.2 mmol/L)
• C. 108 mg/dL (6 mmol/L)
• D. 119 mg/dL (6.6 mmol/L)

Correct answer: A

Rationale: A blood glucose level of 59 mg/dL (3.3 mmol/L) is considered hypoglycemia, which is an abnormally low blood sugar level. This level requires immediate attention as it can lead to symptoms such as confusion, shakiness, and even loss of consciousness if left untreated. Choices B, C, and D have blood glucose levels within the normal range or slightly higher, indicating euglycemia or normal blood sugar levels, and not hypoglycemia.
