A nurse is preparing to screen a client's vision with the use of a Snellen chart. The nurse uses which technique?
- A. Tests the right eye, then tests the left eye, and finally tests both eyes together
- B. Assesses both eyes together, then assesses the right and left eyes separately
- C. Asks the client to stand 40 feet from the chart and read the largest line on the chart
- D. Asks the client to stand 40 feet from the chart and read the line that can be read 200 feet away by someone with unimpaired vision
Correct Answer: A
Rationale: To test visual acuity with the use of a Snellen chart, the nurse places the chart in a well-lit spot at the client's eye level, with the client positioned exactly 20 feet from the chart. The client shields one eye at a time with an opaque card during the test. After testing each eye separately, both eyes are assessed together. The client is asked to read the smallest line of letters visible and encouraged to read the next smallest line as well. Therefore, option A is correct as it describes the correct technique of testing one eye at a time before assessing both eyes together. Option B is incorrect as it assesses both eyes together first, which is not the standard procedure. Options C and D are incorrect as they suggest standing 40 feet from the chart, which contradicts the standard distance of 20 feet for a Snellen chart test.

An adult client tells the clinic nurse that he is susceptible to middle ear infections. About which risk factor related to infection of the ears does the nurse question this client?
- A. Loud music
- B. Use of power tools
- C. Occupational noise
- D. Exposure to cigarette smoke
Correct Answer: D
Rationale: The correct answer is 'Exposure to cigarette smoke.' Otitis media (middle ear infection) is associated with various factors like colds, allergies, sore throats, and blockage of the eustachian tubes. Risk factors include exposure to cigarette smoke, youth (as otitis media is usually a childhood disease), congenital abnormalities, immune deficiencies, family history of otitis media, recent upper respiratory infections, and allergies. Choices A, B, and C (Loud music, Use of power tools, and Occupational noise) are more likely to cause hearing loss rather than being direct risk factors for middle ear infections.
A client has been taking a drug (Drug A) that is highly metabolized by the cytochrome p-450 system. He has been on this medication for 6 months. At this time, he is started on a second medication (Drug B) that is an inducer of the cytochrome p-450 system. You should monitor this client for:
- A. increased therapeutic effects of Drug A.
- B. increased adverse effects of Drug B.
- C. decreased therapeutic effects of Drug A.
- D. decreased therapeutic effects of Drug B.
Correct Answer: C
Rationale: Drug B induces the cytochrome p-450 enzyme system of the liver, thus increasing the metabolism of Drug A, reducing its therapeutic effects.
When a 25-year-old client complains of chest congestion and cough after previously presenting with cold symptoms, what data should the nurse collect?
- A. Data related to follow-up care
- B. A complete health database
- C. Data related to the respiratory system
- D. Data related to the treatment for the cold
Correct Answer: C
Rationale: In this case, the nurse should collect data related to the respiratory system since the client is presenting with symptoms like chest congestion and cough, indicating a respiratory issue. Focusing on the respiratory system will help gather pertinent information to assess the current problem comprehensively. A complete health database involves a detailed health history and full physical examination, which is beyond the immediate scope of the presenting issue. Data related to follow-up care is premature as the primary focus should be on assessing the current respiratory symptoms. Data related to the treatment for the cold is not the priority at this stage, as understanding the underlying respiratory problem is crucial for appropriate intervention.
While assisting with data collection on a client, a nurse hears a bruit over the abdominal aorta. What action should the nurse prioritize based on this finding?
- A. Document the finding
- B. Palpate the area for a mass
- C. Notify the healthcare provider
- D. Percuss the abdomen to check for tympany
Correct Answer: C
Rationale: Detection of a bruit over the aorta during abdominal assessment may indicate the presence of an aneurysm. The nurse's priority action should be to notify the healthcare provider to further evaluate the situation. Palpating the area or percussing the abdomen could potentially increase the risk of an aneurysm rupture. While documenting the finding is important, the priority is to ensure timely intervention by involving the healthcare provider.
When inspecting the ears for cerumen impaction, the nurse checks for which finding?
- A. Redness and swelling of the tympanic membrane
- B. An external auditory canal that is longer than normal
- C. The presence of edema in the external auditory canal
- D. A yellowish or brownish waxy material in the external auditory canal
Correct Answer: D
Rationale: When inspecting the ears for cerumen impaction, the nurse should look for a yellowish or brownish waxy material in the external auditory canal. Cerumen, also known as ear wax, is a secretion that can become impacted due to various reasons. It is produced by the vestigial apocrine sweat glands in the external ear canal. Cerumen may partially obscure the eardrum or totally occlude the ear canal. The other options, redness and swelling of the tympanic membrane, an external auditory canal that is longer than normal, and the presence of edema in the external auditory canal, are not indicative findings of cerumen impaction.
