Nursing Elites

1. A nurse is assessing a client who has asthma. Which of the following areas should the nurse evaluate as the most reliable indicator of central cyanosis?

• A. Oral mucosa
• B. Conjunctivae
• C. Soles of the feet
• D. Ear lobes

Correct answer: A

Rationale: Central cyanosis is best assessed by examining the oral mucosa, as it is a more reliable indicator compared to other areas like the conjunctivae, soles of the feet, and ear lobes. The oral mucosa reflects the oxygen saturation levels of the blood more accurately. Conjunctivae and ear lobes may show cyanosis, but they are not as reliable as the oral mucosa. The soles of the feet are not typically used to assess central cyanosis.

2. Which action by the nurse will help prevent ventilator-associated pneumonia (VAP) in a patient on mechanical ventilation?

• A. Provide oral care every 4 hours.
• B. Reposition the patient every 2 hours.
• C. Suction the patient as needed.
• D. Administer antibiotics as prescribed.

Correct answer: A

Rationale: The correct answer is A. Providing oral care every 4 hours helps prevent ventilator-associated pneumonia by reducing the buildup of bacteria in the mouth that can be aspirated into the lungs. Repositioning the patient every 2 hours is important for preventing pressure ulcers but is not directly related to preventing VAP. Suctioning the patient as needed is essential for maintaining airway patency but does not specifically prevent VAP. Administering antibiotics as prescribed is a treatment for infections but does not prevent VAP.

3. How can a healthcare provider prevent pressure ulcers in an immobile patient?

• A. Turn the patient every 4 hours.
• B. Provide the patient with a special mattress.
• C. Elevate the patient's legs to reduce pressure.
• D. Limit the patient's movement to reduce friction.

Correct answer: B

Rationale: Providing the immobile patient with a special mattress is an effective way to prevent pressure ulcers. Special mattresses help distribute pressure evenly and reduce the risk of developing pressure ulcers by relieving pressure on sensitive areas. Turning the patient every 4 hours (Choice A) is a standard practice to prevent pressure ulcers but may not be as effective as using a special mattress. Elevating the patient's legs (Choice C) can help with circulation but may not directly prevent pressure ulcers. Limiting the patient's movement (Choice D) can lead to other complications and is not a recommended method for preventing pressure ulcers.

4. A nurse in the PACU is caring for a client who has received general anesthesia and has a manifestation of malignant hyperthermia. The nurse should expect to administer which of the following medications?

• A. Acetaminophen
• B. Ibuprofen
• C. Dantrolene
• D. Diazepam

Correct answer: C

Rationale: Corrected Rationale: Dantrolene is the medication of choice to treat malignant hyperthermia, a life-threatening reaction to general anesthesia. It works by inhibiting the release of calcium ions in skeletal muscle cells, preventing muscle contracture and hypermetabolism. Acetaminophen (Choice A) and ibuprofen (Choice B) are not indicated for treating malignant hyperthermia. Diazepam (Choice D) may be used to control muscle spasms but is not the first-line treatment for malignant hyperthermia.

5. A nurse is providing discharge instructions to a client who has a new prescription for codeine for cough suppression. What is the priority instruction?

• A. Avoid driving
• B. Drink plenty of fluids
• C. Move slowly when standing up
• D. Take with food

Correct answer: C

Rationale: The correct answer is to instruct the client to 'Move slowly when standing up.' Codeine can cause orthostatic hypotension, a drop in blood pressure when changing positions, leading to dizziness or fainting. By advising the client to move slowly when standing up, the nurse helps prevent falls or injuries due to sudden drops in blood pressure. Choices A, B, and D are important instructions as well but not the priority when considering the risk of orthostatic hypotension associated with codeine.
