Nursing Elites

1. A client asks a nurse about their Snellen eye test results. The client's visual acuity is 20/30. Which of the following responses should the nurse make?

• A. “Your eyes see at 20 feet what visually unimpaired eyes see at 30 feet.”
• B. “Your right eye can see the chart clearly at 20 feet, and your left eye can see the chart clearly at 30 feet.”
• C. “Your eyes see at 30 feet what visually unimpaired eyes see at 20 feet.”
• D. “Your left eye can see the chart clearly at 20 feet, and your right eye can see the chart clearly at 30 feet.”

Correct answer: A

Rationale: The correct answer is A: 'Your eyes see at 20 feet what visually unimpaired eyes see at 30 feet.' In the Snellen eye test, a visual acuity of 20/30 means that the client sees at 20 feet what a person with normal vision sees at 30 feet. This indicates that the client's vision is slightly worse than average. Choice B is incorrect as it incorrectly describes the visual acuity of each eye individually, rather than the combined visual acuity. Choice C is incorrect as it misinterprets the meaning of the Snellen eye test results by reversing the values. Choice D is incorrect as it inaccurately describes the visual acuity of the client's eyes, attributing different visual acuities to each eye instead of a combined measurement as indicated by 20/30.

2. A client who has a new prescription for warfarin (Coumadin) is receiving discharge instructions. Which statement indicates the client understands the teaching?

• A. I will take my warfarin at the same time every day.
• B. I should increase my intake of green leafy vegetables.
• C. I should use a soft-bristled toothbrush while taking this medication.
• D. I should avoid drinking alcohol while taking this medication.

Correct answer: C

Rationale: The correct answer is C: 'I should use a soft-bristled toothbrush while taking this medication.' Using a soft-bristled toothbrush is crucial as it helps prevent bleeding gums, which is a potential side effect of warfarin therapy. Option A about taking warfarin at the same time every day is a good practice but does not directly relate to preventing side effects. Option B suggesting an increase in green leafy vegetables can interfere with warfarin's anticoagulant effects due to their vitamin K content. Option D advising to avoid alcohol is generally recommended but is not directly related to the specific side effects of warfarin.

3. A client is being discharged home with oxygen therapy via a nasal cannula. Which of the following instructions should the nurse provide to the client and family?

• A. Wear cotton clothing to avoid static electricity.
• B. Avoid using any electrical appliances.
• C. Keep the oxygen tank away from heat sources.
• D. Use only a specific type of nasal cannula.

Correct answer: A

Rationale: The correct answer is A: Wear cotton clothing to avoid static electricity. When using oxygen therapy, static electricity can pose a hazard as it increases the risk of fire. Cotton clothing helps reduce static electricity buildup. Choice B, avoiding electrical appliances, is overly restrictive and not entirely necessary. Choice C, keeping the oxygen tank away from heat sources, is important to prevent fire hazards but is not directly related to the nasal cannula. Choice D, using only a specific type of nasal cannula, is not a universal guideline and limits flexibility in care.

4. During an admission history, a client tells a nurse that she is under a lot of stress. Which of the following physiological responses should the nurse expect to increase as a result of stress?

• A. Blood glucose - a common stress response.
• B. Intestinal peristalsis - should decrease due to stress.
• C. Peripheral blood vessels diameter - can vary in response to stress.
• D. Urine output - may vary but not a typical stress response.

Correct answer: A

Rationale: The correct answer is A. Stress typically increases blood glucose levels due to the release of stress hormones like cortisol and adrenaline. Elevated blood glucose helps provide energy for the body to cope with the stressful situation. Choice B is incorrect because intestinal peristalsis, the movement of the intestines, is more likely to decrease under stress due to the 'fight or flight' response. Choice C is incorrect as peripheral blood vessels' diameter may vary in response to stress, with both constriction and dilation possible. Choice D is incorrect as urine output may increase or decrease depending on individual differences and the specific stress response, but it is not a typical or direct physiological response to stress.

5. A client with a history of hypertension is prescribed a beta-blocker. Which side effect should the LPN/LVN monitor for in this client?

• A. Increased appetite
• B. Dry mouth
• C. Bradycardia
• D. Insomnia

Correct answer: C

Rationale: The correct side effect that the LPN/LVN should monitor for in a client prescribed a beta-blocker is bradycardia. Beta-blockers work by slowing down the heart rate, which can lead to bradycardia as a common side effect. Monitoring the client's heart rate is crucial, as bradycardia can be a serious condition. Choices A, B, and D are incorrect because increased appetite, dry mouth, and insomnia are not typically associated with beta-blockers. Increased appetite is more commonly linked to certain medications like corticosteroids, dry mouth can be a side effect of anticholinergic medications, and insomnia may be a side effect of stimulant medications.
