Nursing Elites

1. A client with heart failure has a prescription for digoxin. The nurse is aware that sufficient potassium should be included in the diet because hypokalemia in combination with this medication:

• A. Can predispose to dysrhythmias
• B. May lead to oliguria
• C. May cause irritability and anxiety
• D. Sometimes alters consciousness

Correct answer: A

Rationale: The correct answer is A: Hypokalemia increases the risk of dysrhythmias when taking digoxin, making potassium intake crucial. Digoxin toxicity is more likely in patients with low potassium levels, leading to an increased risk of dysrhythmias. Choices B, C, and D are incorrect because hypokalemia in combination with digoxin is primarily associated with dysrhythmias rather than oliguria, irritability, anxiety, or alteration of consciousness.

2. A client with a history of seizures is being monitored with an electroencephalogram (EEG). Which of these interventions should the nurse perform to prepare the client for the test?

• A. Instruct the client to avoid caffeine for 8 hours before the test
• B. Explain the procedure to the client and obtain consent
• C. Administer anticonvulsant medication as ordered
• D. Instruct the client to wash their hair the morning of the test

Correct answer: A

Rationale: Instructing the client to avoid caffeine for 8 hours before the EEG is essential. This intervention helps ensure accurate test results by preventing stimulation of the nervous system, which could interfere with the interpretation of the brain's electrical activity. Explaining the procedure and obtaining consent are important steps but do not directly impact the test results. Administering anticonvulsant medication as ordered is a medical intervention and not a preparation step for the test. Instructing the client to wash their hair the morning of the test is not necessary for EEG preparation.

3. To prevent unnecessary hypoxia during suctioning of a tracheostomy, what must the nurse do?

• A. Apply suction for no more than 10 seconds
• B. Maintain a sterile technique
• C. Lubricate 3 to 4 inches of the catheter tip
• D. Withdraw the catheter in a circular motion

Correct answer: A

Rationale: To prevent unnecessary hypoxia during suctioning of a tracheostomy, the nurse must apply suction for no more than 10 seconds. Prolonged suctioning can lead to hypoxia by removing too much oxygen from the patient. Maintaining a sterile technique (choice B) is important to prevent infection but does not directly relate to preventing hypoxia. Lubricating the catheter tip (choice C) helps with the insertion process but does not specifically address hypoxia prevention. Withdrawing the catheter in a circular motion (choice D) is not a standard practice during tracheostomy suctioning and does not contribute to preventing hypoxia.

4. The healthcare provider should recognize which of the following as an indication of dehydration in an elderly client?

• A. Skin turgor
• B. Dry mucous membranes
• C. Elevated temperature
• D. Increased pulse pressure

Correct answer: B

Rationale: Dry mucous membranes are a classic sign of dehydration, especially in elderly individuals. Dehydration can lead to decreased moisture in the mucous membranes, making them dry. Skin turgor, although commonly assessed for dehydration in younger individuals, may be less reliable in the elderly due to changes in skin elasticity. Elevated temperature is more indicative of an infection or other conditions. Increased pulse pressure is not typically associated with dehydration in the elderly.

5. A 4-year-old has been hospitalized for 24 hours with skeletal traction for treatment of a fracture of the right femur. The nurse finds that the child is now crying and the right foot is pale with the absence of a pulse. What should the nurse do first?

• A. Notify the healthcare provider
• B. Readjust the traction
• C. Administer the ordered PRN medication
• D. Reassess the foot in fifteen minutes

Correct answer: A

Rationale: In this situation, a pale foot with the absence of a pulse indicates compromised circulation, which is a critical emergency. The nurse should immediately notify the healthcare provider to address the circulation issue promptly. Reading the question and understanding the urgency is vital. Readjusting the traction, administering PRN medication, or waiting to reassess the foot in fifteen minutes are not appropriate actions when a child is experiencing compromised circulation.
