Nursing Elites

1. You are caring for a 78-year-old woman who is wondering why she was diagnosed with glaucoma. Although she has several risk factors, which of these is not one of them?

• A. age
• B. blood pressure reading of 143/89
• C. Mexican-American heritage
• D. 20/80 vision

Correct answer: D

Rationale: Age over 60 and Mexican-American heritage are recognized as risk factors for glaucoma. Elevated blood pressure is also a risk factor due to its potential to cause optic nerve damage. While 20/80 vision indicates poor eyesight, it is not a direct causal factor for glaucoma. Glaucoma is mainly associated with factors like age, ethnicity, and certain medical conditions, rather than a specific visual acuity measurement. Therefore, 20/80 vision is not a risk factor for glaucoma, making it the correct answer. The other choices, such as age, Mexican-American heritage, and elevated blood pressure, are established risk factors for developing glaucoma, as they are associated with an increased likelihood of the condition.

2. Which of the following statements, if made by the parents of a newborn, does not indicate a need for further teaching about cord care?

• A. "I should put alcohol on my baby's cord 3-4 times a day."?
• B. "I should put the baby's diaper on so that it covers the cord."?
• C. "I should call the physician if the cord becomes dark."?
• D. "I should wash my hands before and after I take care of the cord."?

Correct answer: A

Rationale: Explanation: Parents should be taught that putting alcohol or other antimicrobials on the cord is no longer recommended for cord care. This can interfere with the natural healing process and may increase the risk of irritation or infection. Washing hands before and after providing cord care is essential to prevent the transfer of pathogens. Placing the baby's diaper below the cord allows it to be exposed to air and promotes drying, reducing the risk of infection. It is normal for the cord to turn dark as it dries, so calling the physician only if the cord becomes red, swollen, or has discharge is appropriate. Therefore, the statement '"I should put alcohol on my baby's cord 3-4 times a day."?' indicates a need for further teaching about cord care.

3. The nurse is teaching parents of a newborn about feeding their infant. Which of the following instructions should the nurse include?

• A. Use the defrost setting on microwave ovens to warm bottles.
• B. When refrigerating formula, discard partially used bottles after 24 hours.
• C. When using formula concentrate, mix one part concentrate and two parts water.
• D. If a portion of one bottle is left for the next feeding, discard it.

Correct answer: B

Rationale: The correct answer is to use the defrost setting on microwave ovens to warm bottles. It is crucial to be cautious when heating bottles in a microwave to prevent milk from becoming superheated. The defrost setting is recommended, and the formula's temperature should always be checked before feeding the baby. Choice B, which advises to discard partially used bottles of refrigerated formula after 24 hours, is also correct. This is important to prevent the introduction of pathogens by the baby into the formula. Choice C, recommending mixing one part formula concentrate with two parts water, is essential for ensuring the correct dilution. Choice D, suggesting to discard any remaining portion of a bottle for the next feeding, is incorrect. It is not necessary to discard the remaining portion if it has been refrigerated promptly and used within a safe time frame. Adding fresh formula to a partially used bottle is not recommended, as it can lead to the growth of pathogens that may be transferred to the new formula.

4. 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.

5. 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.
