a client reports feeling dizzy and light headed when standing up what is the nurses best initial action

HESI LPN

Adult Health Exam 1

1. A client reports feeling dizzy and light-headed when standing up. What is the nurse's best initial action?

A. Instruct the client to sit or lie down
B. Monitor blood pressure and pulse
C. Administer an anti-dizziness medication
D. Increase fluid intake

Correct answer: B

Rationale: The correct answer is B: Monitor blood pressure and pulse. When a client reports feeling dizzy and light-headed when standing up, the nurse's best initial action should be to monitor the client's blood pressure and pulse. These symptoms are indicative of orthostatic hypotension, which can be confirmed by changes in blood pressure and pulse when moving from lying to standing positions. Instructing the client to sit or lie down may provide temporary relief but does not address the underlying cause. Administering an anti-dizziness medication should not be the initial action without assessing vital signs first. Increasing fluid intake is important for overall health but is not the priority in this situation where vital sign monitoring is needed to assess for orthostatic hypotension.

2. The practical nurse is preparing to administer a prescription for cefazolin (Kefzol) 600 mg IM every six hours. The available vial is labeled, 'Cefazolin (Kefzol) 1 gram,' and the instructions for reconstitution state, 'For IM use add 2 ml sterile water for injection. Total volume after reconstitution = 2.5 ml.' When reconstituted, how many milligrams are in each milliliter of solution?

A. 400 mg/mL
B. 500 mg/mL
C. 450 mg/mL
D. 350 mg/mL

Correct answer: A

Rationale: After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.

3. The client with newly diagnosed peptic ulcer disease (PUD) is being taught about lifestyle modifications. Which instruction should be included?

A. Increase the intake of spicy foods
B. Avoid the use of nonsteroidal anti-inflammatory drugs (NSAIDs)
C. Drink coffee in moderation
D. Eat large meals at bedtime

Correct answer: B

Rationale: The correct instruction to include when teaching a client with newly diagnosed PUD about lifestyle modifications is to avoid the use of nonsteroidal anti-inflammatory drugs (NSAIDs). NSAIDs can exacerbate peptic ulcer disease by causing further irritation of the gastric mucosa. Increasing the intake of spicy foods (choice A) can aggravate the condition by irritating the stomach lining. Drinking coffee (choice C) can stimulate gastric acid secretion, which may worsen the symptoms of PUD. Eating large meals at bedtime (choice D) can also exacerbate PUD by increasing gastric acid production when the body is at rest, potentially leading to discomfort and symptoms.

4. When observing a newly admitted elderly client with dementia resisting care, what approach should the nurse take to facilitate cooperation?

A. Use short, simple sentences and maintain a calm demeanor
B. Involve family members to provide reassurance
C. Offer choices to empower the client
D. All of the above

Correct answer: D

Rationale: When dealing with a newly admitted elderly client with dementia who is resistant to care, it is crucial to employ multiple strategies to facilitate cooperation. Using short, simple sentences and maintaining a calm demeanor can help the client better understand instructions and reduce agitation. Involving family members can provide comfort and reassurance to the client, potentially decreasing resistance. Offering choices allows the client to feel a sense of control and autonomy in their care, which can increase cooperation and reduce challenging behaviors. Therefore, a combination of clear communication, family involvement, and providing choices is essential to effectively engage and care for a client with dementia. Choices A, B, and C all play crucial roles in addressing the needs of the client, making 'All of the above' the correct answer.

5. A 9-year-old is receiving vancomycin 400 mg IV every 6 hours for a methicillin-resistant (Beta-lactam-resistant) Staphylococci aureus (MRSA) infection. The medication is diluted in a 100 mL bag of saline with instructions to infuse over one and a half hours. How many mL/hour should the nurse program the infusion pump?

A. 50
B. 67
C. 57
D. 70

Correct answer: B

Rationale: To calculate the infusion rate for vancomycin, you need to divide the total volume by the total time of infusion. In this case, the total volume is 100 mL, and the total time is 1.5 hours. Therefore, 100 mL ÷ 1.5 hours = 67 mL/hour. This means the nurse should program the infusion pump to deliver vancomycin at a rate of 67 mL/hour. Choice A (50) is incorrect as it does not reflect the correct calculation. Choice C (57) is incorrect as it is not the accurate calculation based on the provided information. Choice D (70) is incorrect as it does not correspond to the correct infusion rate calculation.
