Nursing Elites

1. The nurse provides a postoperative client with an analgesic medication and darkens the room before the client goes to sleep for the night. The nurse's actions:

• A. help decrease stimuli from the cerebral cortex.
• B. stimulate hormonal changes in the brain.
• C. help the client's circadian rhythm.
• D. alert the hypothalamus in the brain.

Correct answer: A

Rationale: The nurse's actions of providing an analgesic medication and darkening the room aim to decrease stimuli from the cerebral cortex. Reduction of environmental stimuli, especially light and noise, from the cerebral cortex, which is an area of arousal, facilitates sleep. By decreasing input to this area, the client is more likely to fall asleep and stay asleep. Choices B, C, and D are incorrect because the scenario does not involve stimulating hormonal changes, influencing the circadian rhythm, or alerting the hypothalamus.

2. When are pressure ulcers most likely to occur?

• A. when clients are left in one position in bed for extended periods of time.
• B. when clients are underweight.
• C. when clients are overweight.
• D. only in underweight and overweight clients.

Correct answer: A

Rationale: Pressure ulcers usually occur over bony prominences and are caused by decreased circulation. The client who is left in one position in bed for extended periods of time is more prone to decreased circulation to an area of the body and to acquiring a pressure ulcer. Choices B and C are incorrect as pressure ulcers are not exclusive to underweight or overweight clients. The key factor is prolonged pressure on the skin, not the weight of the client. Therefore, the correct answer is that pressure ulcers are most likely to occur when clients are immobilized in one position for extended periods of time.

3. What is the role of the incident report in risk management?

• A. Liability protection.
• B. To provide data for analysis by a risk manager to determine how future problems can be avoided.
• C. To discipline staff for errors.
• D. All of the above.

Correct answer: B

Rationale: The correct answer is 'To provide data for analysis by a risk manager to determine how future problems can be avoided.' Incident reports are a crucial tool for collecting information about incidents to analyze them and prevent similar issues in the future. They are not primarily used for liability protection or disciplining staff. Therefore, choices A and C are incorrect. Selecting 'All of the above' (choice D) is not accurate as incident reports serve a specific purpose related to data analysis and risk prevention, excluding liability protection and staff discipline.

4. Which of the following isoenzymes is elevated in a client who has had a myocardial infarction?

• A. CPK-BB
• B. CPK-MM
• C. CPK-MB
• D. CPK-MI

Correct answer: C

Rationale: CPK-MB is the correct answer as it is elevated in clients who have had a myocardial infarction. CPK-BB is elevated in clients with brain damage, and CPK-MM is elevated in clients with skeletal muscle damage. CPK-MI, mentioned in the rationale, does not exist, making it an incorrect choice.

5. When the healthcare provider is determining the appropriate size of a nasopharyngeal airway to insert, which body part should be measured on the client?

• A. corner of the mouth to tragus of the ear
• B. corner of the eye to top of the ear
• C. tip of the chin to the sternum
• D. tip of the nose to the earlobe

Correct answer: D

Rationale: A nasopharyngeal airway is measured from the tip of the nose to the earlobe. This measurement ensures that the airway is of the correct length to reach the nasopharynx without being too long or too short. Choices A, B, and C are incorrect as they do not provide the appropriate measurement for selecting the correct size of a nasopharyngeal airway. The distance from the corner of the mouth to the tragus of the ear (Choice A) is used to measure for an oropharyngeal airway, not a nasopharyngeal airway. Similarly, the other choices (B and C) do not correlate with the correct measurement of a nasopharyngeal airway.
