A nurse is preparing to administer potassium chloride 10 mEq IV over 1 hr to a client. Available in potassium chloride 10 mEq in 100 mL of 0.9% sodium chloride. The nurse should set the infusion pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.).

10 mL/hr.

50 mL/hr.

100 mL/hr.

500 mL/hr.

Answer and Explanation

The Correct Answer is C

Choice A rationale:
10 mL/hr would be the correct infusion rate if the client was receiving the entire 10 mEq of potassium chloride in a 100 mL solution over 1 hour. However, the question asks for the rate at which to administer 10 mEq over 1 hour, which means the total volume should be 100 mL/hr.
Choice B rationale:
50 mL/hr would be the correct infusion rate if the client was receiving the entire 10 mEq of potassium chloride in a 100 mL solution over 2 hours. However, the question specifies 1 hour, so the rate should be higher.
Choice C rationale:
This is the correct answer. To administer 10 mEq of potassium chloride in 100 mL over 1 hour, the infusion pump should be set to deliver 100 mL/hr.
Choice D rationale:
500 mL/hr would be the correct infusion rate if the client was receiving the entire 10 mEq of potassium chloride in a 100 mL solution over 10 minutes (1/6th of an hour). However, the question specifies 1 hour, so the rate should be much lower.

Correct Answer is A

Explanation

Choice A rationale:
Wearing gloves when changing the cat's litter box is essential during chemotherapy because some chemotherapy drugs can be excreted in bodily fluids, including feces. Protecting against direct contact with potentially harmful substances is crucial to minimize exposure risks.
Choice B rationale:
Taking the temperature once each week is not a relevant precaution during chemotherapy. Monitoring temperature is important, but it should be done more frequently, such as daily, as chemotherapy can cause immunosuppression, increasing the risk of infection.
Choice C rationale:
Being able to attend a concert is not related to precautions during chemotherapy. It is essential for clients undergoing chemotherapy to avoid large gatherings and events where they might be exposed to infections.
Choice D rationale:
Allowing the toothbrush to dry completely between each use is a good hygiene practice but not specifically related to chemotherapy precautions. Proper oral hygiene is essential during chemotherapy, but using a soft toothbrush and regularly replacing it are more relevant considerations.

A. Prolonged sun exposure. B. Reduced intake of vitamin E. C. Drinking one glass of wine per day. D. Exposure to second-hand tobacco smoke.

Correct Answer is ["A","D"]

Explanation

Choice A rationale:

Prolonged sun exposure is a risk factor for osteoporosis because it can lead to vitamin D deficiency. Vitamin D is essential for calcium absorption, and low levels of vitamin D can contribute to reduced bone density and increased risk of fractures.

Choice B rationale:

Reduced intake of vitamin E is not a well-established risk factor for osteoporosis. Vitamin E is an antioxidant and plays a role in various bodily processes, but its association with osteoporosis is not supported by strong evidence.

Choice C rationale:

Drinking one glass of wine per day is not a risk factor for osteoporosis. In fact, moderate alcohol consumption has been suggested to have a protective effect on bone density in some studies.

Choice D rationale:

Exposure to second-hand tobacco smoke is a risk factor for osteoporosis. Smoking and exposure to tobacco smoke have been linked to decreased bone density and increased risk of fractures, making this an important point to include in the teaching.
