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.

Which of the following enzymes is indicative of pancreatitis?
- A. alkaline phosphatase
- B. acid phosphatase
- C. creatine phosphokinase
- D. amylase
Correct Answer: D
Rationale: Amylase is elevated in conditions of pancreatic inflammation, such as pancreatitis. Pancreatitis is characterized by the inflammation of the pancreas, leading to the leakage of amylase into the bloodstream. Elevated levels of amylase are a key diagnostic marker for pancreatitis. Alkaline phosphatase is associated with liver and bone conditions, not pancreatitis. Acid phosphatase is more related to prostate health and is not specific to pancreatitis. Creatine phosphokinase is found in tissues like muscle and brain, and elevated levels are seen in conditions like muscle injury or heart attack, not pancreatitis.
The nurse notices that a family is waiting at the nursing station desk for its loved one to be brought to the unit for admission during a change-of-shift report. The nurse should:
- A. request that the family wait for its loved one in the client's room and wait to resume the report until the family has left the desk area.
- B. request that a nursing assistant bring coffee for the family while it waits at the desk and continue with the report.
- C. request that the family have a seat in the station rather than stand while awaiting its loved one.
- D. request that the family wait for its loved one in the Emergency Department waiting room.
Correct Answer: A
Rationale: To protect the privacy of clients and the confidentiality of the information shared in a change-of-shift report, the family should be asked to wait in the client's room. This ensures that sensitive information is not overheard. The report should be resumed only after the family has left the desk area to maintain confidentiality. Choice B is incorrect as bringing coffee does not address the issue of maintaining confidentiality. Choice C is incorrect as standing or sitting in the station does not prevent the family from overhearing confidential information. Choice D is incorrect as the Emergency Department waiting room is not the appropriate setting for waiting during a unit admission.
Following an automobile accident that caused a head injury to an adult client, the nurse observes that the client sleeps for long periods of time. The nurse determines that the client has experienced injury to the:
- A. hypothalamus.
- B. thalamus.
- C. cortex.
- D. medulla.
Correct Answer: A
Rationale: The hypothalamus is responsible for regulating sleep patterns among other functions. Injury to the hypothalamus can disrupt the sleep-wake cycle, leading to excessive sleepiness or changes in sleep patterns. Choices B, C, and D are incorrect as they do not primarily control sleep regulation. The thalamus is involved in relaying sensory information, the cortex is responsible for higher brain functions, and the medulla controls vital functions such as heartbeat and breathing.
A client with a nasogastric (NG) tube begins vomiting. What action should the nurse take?
- A. Retape the NG tube.
- B. Clamp the NG tube.
- C. Remove the NG tube.
- D. Check the NG tube placement.
Correct Answer: D
Rationale: When a client with a nasogastric (NG) tube begins vomiting, the nurse should first check the NG tube placement. Vomiting can be a sign of tube displacement, which can lead to serious complications. Retaping the tube (Choice A), clamping it (Choice B), or removing it (Choice C) without first assessing its placement can be harmful or ineffective. Checking the NG tube placement is crucial as it ensures that the tube is in the correct position and prevents potential complications. Retaping the NG tube (Choice A) is incorrect because the priority is to check the placement first. Clamping the NG tube (Choice B) or removing it (Choice C) without verifying the placement can be dangerous if the tube is dislodged. Thus, these actions should not be taken before confirming the tube's position.
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.
