Nursing Elites

1. 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.

2. A nurse is telling a pregnant client about the signs that must be reported to the health care provider. The nurse tells the client that the health care provider should be contacted if which occurs?

• A. Puffiness of the face
• B. Breast tenderness
• C. Morning sickness
• D. Urinary frequency

Correct answer: A

Rationale: During pregnancy, it is important to be aware of danger signs that warrant contacting the healthcare provider. Puffiness of the face, especially around the eyes, can indicate a serious condition like preeclampsia. Other danger signs include vaginal bleeding, rupture of membranes, severe abdominal pain, visual disturbances, persistent vomiting, and changes in fetal movements. Morning sickness, breast tenderness, and urinary frequency are common symptoms of pregnancy and are not typically concerning unless they become severe or persistent, and do not usually require immediate medical attention.

3. A nurse is preparing to assess the function of a client's spinal accessory nerve. Which action does the nurse ask the client to take to aid assessment of this nerve?

• A. Smiling
• B. Clenching the teeth
• C. Shrugging the shoulders against the nurse's resistance
• D. Identifying by taste a substance placed on the back of the tongue

Correct answer: C

Rationale: To assess cranial nerve XI (spinal accessory nerve), the examiner checks the sternomastoid and trapezius muscles for equal size. Equal strength is assessed by asking the client to rotate the head forcibly against resistance applied to the side of the chin and by asking the client to shrug the shoulders against resistance. These movements should feel equally strong on the two sides. The client is asked to smile as a test of the function of cranial nerve VII (facial nerve). The client's ability to clench the teeth is used to assess the motor function of cranial nerve V (trigeminal nerve). The client's taste perception is used to assess the sensory function of cranial nerve IX (glossopharyngeal nerve). Therefore, the correct action to assess the spinal accessory nerve is to ask the client to shrug the shoulders against resistance. The other options are used to assess different cranial nerves, making them incorrect choices.

4. 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.

5. What effect can medication bound to protein have?

• A. reduced drug availability
• B. limited distribution of the drug to receptor sites
• C. less availability to produce desired medicinal effects
• D. decreased metabolism of the drug by the liver

Correct answer: C

Rationale: Medication bound to protein leads to less availability to produce desired medicinal effects because only unbound drugs can interact with active receptor sites. If a drug is bound to protein, it cannot bind with a receptor site, reducing its effectiveness. Choice A is incorrect because binding to protein reduces drug availability. Choice B is incorrect because distribution to receptor sites is ineffective if the drug is bound to protein. Choice D is incorrect because metabolism does not occur until the drug is removed from the protein molecule by the liver, allowing the protein to return to circulation.
