Nursing Elites

1. After 1 week of hospitalization, Mr. Gray develops hypokalemia. Which of the following is the most significant symptom of his disorder?

• A. Lethargy
• B. Increased pulse rate and blood pressure
• C. Muscle weakness
• D. Muscle irritability

Correct answer: C

Rationale: Muscle weakness is a hallmark symptom of hypokalemia. Hypokalemia refers to low levels of potassium in the blood, which can affect muscle function. The decreased potassium levels can lead to muscle weakness, cramping, and even paralysis. These symptoms can impact various muscle groups in the body, making muscle weakness the most significant symptom to monitor and address in patients with hypokalemia.

2. A healthcare professional is preparing to measure an infant's temperature. Which of the following actions should the healthcare professional take?

• A. Place the tip of the thermometer under the center of the infant's axilla
• B. Pull the pinna of the infant's ear forward before inserting the probe
• C. Insert the probe 3.8 cm (1.5in) into the infant's rectum
• D. Insert the thermometer in front of the infant's tongue

Correct answer: A

Rationale: When measuring an infant's temperature, the most appropriate and non-invasive method is to place the tip of the thermometer under the center of the infant's axilla (armpit). This method is safe, quick, and comfortable for the infant. Inserting the probe into the rectum is invasive and not recommended for routine temperature measurement in infants. Inserting the thermometer in front of the infant's tongue is not a reliable method for measuring temperature. Pulling the pinna of the ear forward is a technique used for adults, not infants.

3. What is the transparent membrane that focuses the light entering the eyes onto the retina?

• A. Lens
• B. Sclera
• C. Cornea
• D. Pupils

Correct answer: A

Rationale: The correct answer is the lens. The lens is a transparent structure in the eye that helps to focus light onto the retina, which is essential for clear vision. The cornea and sclera are also important parts of the eye, but the lens specifically plays a crucial role in focusing light onto the retina. The sclera is the white outer layer of the eye that helps maintain the shape of the eye, while the cornea is the clear outer covering of the eye that helps to refract light into the eye.

4. When a chest tube is accidentally removed from a client, which of the following actions should the nurse NOT take first?

• A. Obtain a chest x-ray
• B. Apply sterile gauze to the insertion site
• C. Place tape around the insertion site
• D. Assess respiratory status

Correct answer: B

Rationale: When a chest tube is accidentally removed, the priority action for the nurse is to immediately seal the insertion site with a gloved hand, a sterile occlusive dressing, or petroleum gauze to prevent air from entering the pleural space and causing a pneumothorax. Applying sterile gauze to the insertion site is not the correct initial action. The first step is to prevent respiratory compromise by ensuring the site is sealed. Therefore, the nurse should not apply sterile gauze to the insertion site first.

5. Which of the following interventions promotes patient safety?

• A. Assess the patient’s ability to ambulate and transfer from a bed to a chair
• B. Demonstrate the signal system to the patient
• C. Check to see that the patient is wearing their identification band
• D. All of the above

Correct answer: D

Rationale: All the listed interventions are essential for promoting patient safety. Assessing the patient’s ability to ambulate and transfer helps prevent falls, demonstrating the signal system ensures effective communication in emergencies, and checking the patient's identification band aids in accurate identification and treatment. By combining these interventions, healthcare providers can enhance patient safety and quality of care.
