A nurse is preparing to administer 0.9% sodium chloride IV infusion 1-L bag at a rate of 125 mL/hr for a client who has rhabdomyolysis. The nurse should expect the IV pump to infuse over how many hours? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["8"]

Calculate the total infusion time:

Total volume (mL) / Infusion rate (mL/hr) = Infusion time (hours)

1000 mL / 125 mL/hr = 8 hours

Therefore, the IV pump should infuse the 1-liter bag of 0.9% sodium chloride over 8 hours.

Correct Answer is D

Explanation

A. Antihistamines can raise blood pressure, but this is less likely to be the primary cause compared to medication non-adherence.

B. Acetaminophen is generally safe for use in hypertensive patients and is unlikely to contribute to the high blood pressure in this scenario.

C. Stress can contribute to elevated blood pressure, but non-adherence to medications is a more likely cause of the severe BP elevation in this case.

D. Poor medication adherence is a common cause of elevated blood pressure despite treatment. If the client has not been consistently taking their antihypertensive medications, this could explain the elevated BP and symptoms (headache, blurred vision).

A. Avoid straining or blowing your nose forcefully. B. Brush your teeth vigorously to avoid gum infections. C. if a dose of the medication is missed, double the dose at the next scheduled time D. Rotate injection sites when on this medication

Correct Answer is A

Explanation

A. Warfarin is an anticoagulant, which increases the risk of bleeding. Activities like straining or forceful nose blowing can increase the risk of bleeding, particularly nasal or internal bleeding, so the nurse should advise the client to avoid these actions.

B. Brushing teeth vigorously is not recommended with warfarin because it can lead to bleeding gums. The nurse should suggest using a soft toothbrush and brushing gently.

C. If a dose of warfarin is missed, the client should not double the dose. They should take the missed dose as soon as they remember, unless it's close to the time for the next dose, in which case they should skip the missed dose and resume the normal dosing schedule.

D. Warfarin is an oral medication, so rotating injection sites is not applicable. This advice is more relevant for injectable medications like insulin or heparin.
