HESI RN CAT Exam Quizlet

Correct Answer: B

Rationale: To calculate the correct dosage, first, determine the total daily dose: 1.5 grams = 1500 mg. Since the medication is 200 mg/5 ml, for 1500 mg, the nurse needs to administer 1500/200 = 7.5 times the 5 ml dose. Therefore, 7.5 x 5 ml = 37.5 ml total daily dose. To administer this every 8 hours, divide 37.5 ml by 3 (8 hours intervals in a day) to get 12.5 ml to be administered every 8 hours. Choice A, C, and D are incorrect as they do not reflect the correct calculation of the dose based on the prescription and the available concentration.

Correct Answer: C

Rationale: Swelling of the fingers can indicate compromised circulation, which is a serious concern in a client with a new cast. It could suggest the development of compartment syndrome, a condition where increased pressure within the muscles can lead to impaired blood flow. This can result in tissue damage and should be addressed promptly. Itching under the cast, pain at the cast site, and warmth over the casted area are common findings after cast application and may not necessarily indicate an urgent issue requiring immediate reporting to the healthcare provider.

Correct Answer: D

Rationale: When obtaining a urine specimen from a female infant, securing the pediatric urine collector bag to the perineum is the most appropriate intervention. This method allows for non-invasive collection of urine without causing discomfort or distress to the infant. Placing the wet diaper in a biohazard specimen bag (Choice A) is incorrect as it does not involve collecting a fresh urine sample. Using a catheter (Choice B) is invasive and not typically necessary for routine urine specimen collection from infants. Collecting the urinary stream in mid-air when the infant cries (Choice C) is not a reliable or hygienic method of obtaining a urine specimen.

Correct Answer: A

Rationale: The correct answer is A. Rifampin (Rifadin) commonly causes a reddish-orange discoloration of body fluids, including urine, sweat, saliva, and tears. This is a harmless side effect but should be reported to the healthcare provider for monitoring. Choices B, C, and D are not typically associated with rifampin therapy. Bloody or blood-tinged urine may indicate other issues such as urinary tract infection or kidney problems, blurring of vision may suggest eye problems, and significant weight gain could be related to various health conditions unrelated to rifampin.

Correct Answer: D

Rationale: The correct answer is D: "Ginseng can increase blood pressure, which is a concern for clients with hypertension." Choice A is incorrect because ginseng does not typically decrease the effectiveness of blood pressure medication. Choice B is incorrect as stopping ginseng while on blood pressure medication may not be necessary. Choice C is not the most direct concern related to ginseng use in a hypertensive client, making it less relevant than the correct answer.
