Extract:
Question 1 of 5
The nurse is assessing a client with suspected tuberculosis. Which precaution should be implemented?
Correct Answer: B
Rationale: Tuberculosis is transmitted via airborne droplets, requiring airborne precautions (e.g., N95 mask, negative pressure room). Standard, droplet, and contact precautions are insufficient.
Question 2 of 5
The nurse is preparing to administer a feeding via a nasogastric tube. The nurse would perform which of the following before initiating the feeding?
Correct Answer: A
Rationale: Verifying nasogastric tube placement by aspirating stomach contents (and checking pH) is critical to prevent aspiration. Left-lying position is incorrect, 50% dextrose is inappropriate, and microwaving can cause burns or nutrient degradation.
Question 3 of 5
The intensive care unit is full and the emergency room just called to report that a client with suspected carbon monoxide poisoning has arrived. Which clinical manifestation would the nurse expect if carbon monoxide poisoning has occurred?
Correct Answer: C
Rationale: Carbon monoxide binds hemoglobin, forming carboxyhemoglobin, causing cherry red mucous membranes. Pulse oximetry (
A) is unreliable, stridor (
B) suggests obstruction, and carbonaceous particles (
D) indicate smoke inhalation.
Question 4 of 5
Which measure helps reduce nipple soreness associated with breastfeeding?
Correct Answer: B
Rationale: Breaking suction by placing a finger between the baby’s mouth and the breast prevents trauma to the nipple, reducing soreness. Feeding early promotes latch but doesn’t address soreness directly, warm soaks may increase inflammation, and a bra supports but doesn’t prevent nipple trauma.
Question 5 of 5
The client has an order for Garamycin (gentamicin) to be administered. Which lab test should be done before beginning the medication?
Correct Answer: B
Rationale: Gentamicin, an aminoglycoside, is nephrotoxic. Serum creatinine is monitored before administration to assess baseline kidney function, as impaired renal function increases toxicity risk. Hematocrit, white cell count, and BUN are less specific for gentamicin.
