Nursing Elites

1. A nurse is reviewing the results of an arterial blood gas analysis of a client who has chronic obstructive pulmonary disease. Which of the following results should the nurse expect?

• A. PaO2 of 95 mm Hg
• B. PaCO2 of 55 mm Hg
• C. HCO3 of 24 mEq/L
• D. pH level of 7.35

Correct answer: B

Rationale: In chronic obstructive pulmonary disease, there is impaired gas exchange, leading to retention of carbon dioxide (CO2) and subsequent respiratory acidosis. A PaCO2 of 55 mm Hg is higher than the normal range (35-45 mm Hg) and is indicative of respiratory acidosis in COPD. Choices A, C, and D are not typically associated with COPD. PaO2 may be decreased, HCO3 may be elevated to compensate for acidosis, and pH may be lower than 7.35 due to respiratory acidosis in COPD.

2. What is the best way to monitor for infection in a patient with a central line?

• A. Check the central line site daily
• B. Monitor the patient's vital signs
• C. Check the central line dressing every other day
• D. Check for signs of sepsis

Correct answer: A

Rationale: The correct answer is A: Check the central line site daily. Monitoring the central line site daily is crucial in detecting early signs of infection, such as redness, swelling, tenderness, or drainage. By checking the site regularly, healthcare providers can take prompt action to prevent complications. Choice B, monitoring the patient's vital signs, while important in assessing overall health, may not specifically indicate an infection related to the central line. Choice C, checking the central line dressing every other day, may not be frequent enough to catch early signs of infection. Choice D, checking for signs of sepsis, is important but represents a more severe stage of infection and may occur after local signs at the central line site have already manifested.

3. A healthcare provider is reviewing the medical records of a client with a prescription for combination oral contraceptives. Which of the following conditions is a contraindication?

• A. Hyperthyroidism
• B. Thrombophlebitis
• C. Diverticulosis
• D. Hypocalcemia

Correct answer: B

Rationale: Thrombophlebitis is a contraindication to combination oral contraceptives due to the increased risk of thromboembolic events. Hyperthyroidism, diverticulosis, and hypocalcemia are not contraindications to combination oral contraceptives. Hyperthyroidism may affect thyroid hormone levels but does not directly contraindicate oral contraceptives. Diverticulosis is a condition related to the digestive system and does not impact the use of oral contraceptives. Hypocalcemia, a low calcium level in the blood, is not a contraindication for oral contraceptives.

4. A nurse is caring for a client who has chronic kidney disease. The nurse should identify which of the following laboratory values as an indication for hemodialysis?

• A. Glomerular filtration rate of 14 mL/min
• B. BUN 16 mg/dL
• C. Serum magnesium 1.8 mg/dL
• D. Serum phosphorus 4.0 mg/dL

Correct answer: A

Rationale: A glomerular filtration rate (GFR) of 14 mL/min is significantly low, indicating poor kidney function and the need for hemodialysis to remove waste products effectively. BUN, serum magnesium, and serum phosphorus levels are important in assessing kidney function and electrolyte balance but are not direct indicators for the initiation of hemodialysis. BUN (blood urea nitrogen) reflects the kidney's ability to filter waste products, serum magnesium levels are important for muscle and nerve function, and serum phosphorus levels are vital for bone health.

5. A nurse is planning care for a client who is postoperative following abdominal surgery. Which of the following interventions should the nurse implement to prevent respiratory complications?

• A. Encourage the client to ambulate twice daily.
• B. Encourage the client to deep breathe and cough every hour.
• C. Encourage the client to use an incentive spirometer every hour.
• D. Instruct the client to avoid coughing to prevent pain.

Correct answer: C

Rationale: The correct answer is C. Encouraging the client to use an incentive spirometer every hour is crucial to prevent respiratory complications postoperatively. Incentive spirometry helps in lung expansion and prevents atelectasis, which is common after abdominal surgery. Choice A, encouraging ambulation, is important for preventing complications but does not directly address respiratory issues. Choice B, deep breathing and coughing every hour, is also beneficial but not as effective in preventing atelectasis as using an incentive spirometer. Choice D, instructing the client to avoid coughing, is incorrect as coughing helps clear secretions and prevent respiratory complications.
