A nurse reviewing a client's record notes that the result of the client's latest Snellen chart vision test was 20/80. The nurse interprets the client's results in which way?
- A. The client is legally blind.
- B. The client has normal vision.
- C. The client can read at a distance of 20 feet what a client with normal vision can read at 80 feet.
- D. The client can read at a distance of 80 feet what a client with normal vision can read at 20 feet.
Correct Answer: D
Rationale: When interpreting visual acuity testing results using the Snellen chart, the recorded numeric fraction represents the distance the client is standing from the chart and the distance a normal eye could read that particular line. A reading of 20/80 means that the client can read at 20 feet what a client with normal vision can read at 80 feet. This indicates visual impairment but does not meet the criteria for legal blindness, which is defined as best-corrected vision in the better eye of 20/200 or worse. Normal visual acuity is 20/20. Therefore, the correct interpretation is that the client can read at a distance of 80 feet what a client with normal vision can read at 20 feet. Choice A is incorrect because 20/80 does not meet the criteria for legal blindness. Choice B is incorrect as the client's vision is impaired. Choice C is incorrect because it reverses the interpretation of the fraction.

The LPN is caring for a client taking Lipitor (Atorvastatin). Which of these statements would indicate that the client may need reinforced teaching?
- A. "I take my Lipitor with a glass of milk after my breakfast."?
- B. "I take my Lipitor and wait 30 minutes before taking my other medications."?
- C. "I take my Lipitor 30 minutes after I eat something."?
- D. "I take my Lipitor and my other morning medications with my grapefruit juice at breakfast."?
Correct Answer: D
Rationale: The correct answer is, 'I take my Lipitor and my other morning medications with my grapefruit juice at breakfast.' This statement indicates a need for reinforced teaching because grapefruit juice should be avoided when taking Lipitor. Grapefruit juice blocks the enzymes needed to break down the drug, which leads to excessive amounts of the drug in the body. Choices A, B, and C show appropriate timing and administration of Lipitor, whereas choice D poses a potential risk due to the interaction between grapefruit juice and Lipitor.
During the examination of a client's throat, a nurse touches the posterior wall with a tongue blade and elicits the gag reflex. The nurse documents normal function of which cranial nerves?
- A. Cranial nerves V and VI
- B. Cranial nerves XII and VIII
- C. Cranial nerves XII and VIII
- D. Cranial nerves IX and X
Correct Answer: D
Rationale: The correct answer is cranial nerves IX (glossopharyngeal nerve) and X (vagus nerve). When the nurse touches the posterior pharyngeal wall with a tongue blade and elicits the gag reflex, it indicates normal function of these nerves. Cranial nerves V (trigeminal nerve) and VI (abducens nerve) are not directly responsible for the gag reflex. Cranial nerves XII (hypoglossal nerve) and VIII (vestibulocochlear nerve) are not directly involved in eliciting the gag reflex. Testing cranial nerve I involves smell function, and cranial nerve II is related to eye examinations, making them irrelevant in this scenario.
During an interview, what action should a nurse conducting an interview with a client take to collect subjective data?
- A. Takes minimal notes to avoid impeding observation of the client's nonverbal behaviors
- B. Takes a great deal of notes to allow the client to continue at his or her own pace as the nurse records what he or she is saying
- C. Takes notes because this allows the nurse to break eye contact with the client, which may increase the client's level of comfort
- D. Takes notes to allow the nurse to shift attention away from the client, which may make the nurse more comfortable
Correct Answer: A
Rationale: During an interview, a nurse should minimize note-taking to focus on the client and not impede the conversation. Taking minimal notes allows the nurse to effectively observe the client's nonverbal behaviors, which provide valuable subjective data. Option B, taking many notes, is incorrect as it can distract the nurse from the client's cues and hinder interaction. Option C, taking notes to break eye contact, is incorrect as it may decrease the client's comfort level and disrupt communication. Option D, taking notes to shift attention away from the client, is incorrect as it diminishes the client's importance and may make them uncomfortable during sensitive discussions. Therefore, the correct approach is for the nurse to take minimal notes, ensuring effective observation of the client's nonverbal behaviors while collecting subjective data.
During data collection of a client with suspected carpal tunnel syndrome, a nurse plans to perform the Phalen test. The nurse should ask the client to perform which activity?
- A. Dorsiflex the foot
- B. Plantarflex the foot
- C. Hold the hands back to back while flexing the wrists 90 degrees for 60 seconds
- D. Hyperextend the fingers with the palmar surfaces of the hands touching, holding the position for 60 seconds
Correct Answer: C
Rationale: In the Phalen test, the nurse asks the client to hold the hands back to back while flexing the wrists 90 degrees. This position puts pressure on the median nerve, eliciting symptoms in carpal tunnel syndrome. Dorsiflexing or plantarflexing the foot and hyperextending the fingers are not associated with testing for carpal tunnel syndrome. Acute flexion of the wrist for 60 seconds produces no symptoms in the normal hand.
How should a nurse listen to the breath sounds of a client?
- A. Ask the client to lie prone.
- B. Ask the client to breathe in and out through the nose.
- C. Hold the bell of the stethoscope lightly against the chest.
- D. Listen for at least one full respiration in each location on the chest.
Correct Answer: D
Rationale: To best listen to breath sounds, the nurse should have the client sit, leaning slightly forward, with arms resting comfortably across the lap. The client should be instructed to breathe through the mouth a little deeper than usual, but to stop if feeling dizzy. The nurse should hold the flat diaphragm end piece of the stethoscope firmly against the client's chest wall. It is crucial to listen for at least one full respiration in each location on the chest to assess breath sounds accurately. Side-to-side comparison is essential in breath sound assessment. Therefore, options A, B, and C are incorrect as they do not align with the correct procedure for listening to breath sounds.
