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. While assisting with data collection, the nurse asks the client to close their jaws tightly. Subsequently, the nurse tries to open the closed jaws. In this technique, the nurse is assessing the motor function of which nerve?

• A. Trochlear nerve
• B. Abducens nerve
• C. Trigeminal nerve
• D. Oculomotor nerve

Correct answer: C

Rationale: The correct answer is C: Trigeminal nerve. To test the motor function of the trigeminal nerve (cranial nerve V), the nurse assesses the muscles of mastication by asking the client to clench their teeth. By trying to separate the client's jaws, the nurse evaluates the strength of the temporal and masseter muscles innervated by the trigeminal nerve. This technique helps assess if the trigeminal nerve is functioning properly. Choices A, B, and D are incorrect because they relate to other cranial nerves that are not involved in the specific motor function being tested in this scenario. These nerves are usually assessed through different examinations such as assessing the pupils and extraocular movements, which are not part of the jaw clenching and opening technique described in the question.

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. The LPN is caring for a 9-month-old infant. Which of these behaviors exhibited by the child warrants further investigation?

• A. She prefers crawling over walking and makes no attempt to walk.
• B. She seems distressed by new adults.
• C. She does not respond to her own name.
• D. She only babbles "mama"? and "dada."?

Correct answer: C

Rationale: The correct answer is that the child does not respond to her own name. By 9 months, children should be babbling simple words, crawling, and responding to their name. Not responding to one's name can be an early indicator of a potential developmental delay, warranting further investigation. Preferring crawling over walking, being distressed by new adults, and babbling 'mama' and 'dada' are typical behaviors for a 9-month-old and do not necessarily require immediate concern.

5. A nurse provides instructions to an older adult about measures to prevent heatstroke. Which statement by the client indicates a need for further instruction?

• A. ''I should wear cool, light clothing in warm weather.''
• B. ''I need to wear a hat with a wide brim when I go outdoors.''
• C. ''I need to wear additional antiperspirant and deodorant in warm weather.''
• D. ''I should drink extra fluids during the summer.''

Correct answer: C

Rationale: As an individual ages, the number of sweat glands decreases, resulting in reduced body odor and decreased evaporative heat loss due to less sweating. The need for antiperspirants and deodorants is reduced in older adults. Therefore, the statement 'I need to wear additional antiperspirant and deodorant in warm weather' indicates a need for further instruction. Older adults should focus on wearing cool, light clothing in warm weather to prevent overheating, wearing a hat with a wide brim when outdoors to protect from the sun's rays, and staying hydrated by drinking extra fluids during the summer. These measures are more effective in preventing heatstroke in older adults compared to using additional antiperspirants and deodorants, which are not necessary.
