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. During a routine clinic visit, a nurse is assessing a 48-year-old client with a history of smoking. The client, who exercises regularly, reports calf pain during exercise that disappears at rest. Which of the following findings requires further evaluation?

• A. Heart rate of 57 bpm.
• B. SpO2 of 94% on room air.
• C. Blood pressure of 134/82.
• D. Ankle-brachial index of 0.65.

Correct answer: D

Rationale: An Ankle-Brachial Index of 0.65 suggests moderate arterial vascular disease in a client experiencing intermittent claudication, indicating compromised blood flow to the lower extremities during exercise. This finding requires further evaluation to assess the severity of arterial insufficiency and determine appropriate interventions. Choice A (Heart rate of 57 bpm) is within the normal range for an adult at rest and indicates good cardiovascular fitness. Choice B (SpO2 of 94% on room air) is slightly lower than the normal range but is generally acceptable in a healthy individual. Choice C (Blood pressure of 134/82) falls within the normal range and does not raise immediate concerns in this context.

3. 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.

4. The nurse assumes care for a patient who is currently receiving a dose of intravenous vancomycin (Vancocin) infusing at 20 mg/min. The nurse notes red blotches on the patient’s face, neck, and chest and assesses a blood pressure of 80/55 mm Hg. Which action will the nurse take?

• A. Request an order for IV epinephrine to treat anaphylactic shock.
• B. Slow the infusion to 10 mg/min and observe the patient closely.
• C. Stop the infusion and obtain an order for a BUN and serum creatinine.
• D. Suspect Stevens-Johnson syndrome and notify the provider immediately.

Correct answer: B

Rationale: When vancomycin is infused too rapidly, “red man” syndrome may occur; the rate should be 10 mg/min to prevent this. This is a toxic reaction, not an allergic one, so epinephrine is not indicated. Stevens-Johnson syndrome is characterized by a rash and fever. Red man syndrome is not related to renal function.

5. Which of the following is a key symptom of hypothyroidism?

• A. Weight loss.
• B. Heat intolerance.
• C. Cold intolerance.
• D. Increased appetite.

Correct answer: C

Rationale: Cold intolerance is a key symptom of hypothyroidism because a decreased metabolic rate leads to a reduced ability to regulate body temperature. Weight loss (Choice A) is more commonly associated with hyperthyroidism, where the metabolic rate is increased. Heat intolerance (Choice B) is also more indicative of hyperthyroidism, where excess thyroid hormone leads to an increased sensitivity to heat. Increased appetite (Choice D) is not typically seen in hypothyroidism; instead, individuals with hypothyroidism may experience weight gain due to the slowed metabolism.
