NCLEX RN Exam Review Answers
1. A patient asks the nurse why they must have a heparin injection. What is the nurse's best response?
- A. Heparin will dissolve clots that you have.
- B. Heparin will reduce the platelets that make your blood clot.
- C. Heparin will work better than warfarin.
- D. Heparin will prevent new clots from developing.
Correct answer: D
Rationale: The correct answer is D: 'Heparin will prevent new clots from developing.' Heparin is an anticoagulant medication that helps prevent the formation of new blood clots. It does not dissolve existing clots (choice A), reduce platelets (choice B), or necessarily work 'better' than warfarin (choice C) but rather functions differently. The primary action of heparin is to prevent the development of new clots, especially in conditions where clot formation is a concern.
2. During an assessment of a client with cardiomyopathy, the nurse finds that the systolic blood pressure has decreased from 145 to 110 mm Hg and the heart rate has risen from 72 to 96 beats per minute, and the client complains of periodic dizzy spells. The nurse instructs the client to:
- A. Increase fluids that are high in protein
- B. Restrict fluids
- C. Force fluids and reassess blood pressure
- D. Limit fluids to non-caffeine beverages
Correct answer: D
Rationale: In this scenario, the client with cardiomyopathy is exhibiting signs of orthostatic hypotension, which is characterized by a significant drop in systolic blood pressure (>15 mm Hg) and an increase in heart rate (>15%), along with dizziness. These symptoms suggest volume depletion, inadequate vasoconstrictor mechanisms, and autonomic insufficiency. The appropriate nursing intervention in this case is to force fluids and reassess blood pressure to address the underlying issue of volume depletion and improve hemodynamic stability. Choices A, B, and D are incorrect because increasing fluids high in protein, restricting fluids, or limiting fluids to non-caffeine beverages are not appropriate actions for a client experiencing orthostatic hypotension and signs of volume depletion.
3. A client had a closed reduction of a fractured right wrist followed by the application of a fiberglass cast 12 hours ago. Which finding requires immediate attention?
- A. Capillary refill of fingers on right hand is 3 seconds
- B. Skin warm to touch and normally colored
- C. Client reports prickling sensation in the right hand
- D. Slight swelling of fingers of right hand
Correct answer: C
Rationale: A prickling sensation in the right hand is indicative of compartment syndrome, a serious condition that can lead to tissue damage and impaired circulation. Immediate attention is required to prevent complications. Capillary refill of 3 seconds, warm and normally colored skin, and slight swelling of fingers are expected findings after a closed reduction and casting. These findings do not typically indicate a critical issue and can be managed with routine monitoring.
4. The parents of an infant who underwent surgical repair of bladder exstrophy ask if the infant will be able to control their bladder as they get older. How should the nurse respond?
- A. Your child will need catheterization until bladder control is gained.
- B. Your child will be able to control their bladder like other children.
- C. You should potty train your child at the same time you normally would.
- D. Your child will not have a sphincter mechanism for the first 3 to 5 years, so urine will drain freely.
Correct answer: D
Rationale: Bladder exstrophy is a congenital defect where the infant is born with the bladder located on the outside of the body. Surgical repair typically occurs within the first 1 to 2 days of life. In the following 3 to 5 years post-surgery, urine will drain freely from the urethra due to the absence of a sphincter mechanism. This period allows the bladder to develop capacity as the child grows. Subsequent surgical interventions will be required to establish a functioning sphincter mechanism. Therefore, the correct response is that the child will not have a sphincter mechanism for the first 3 to 5 years, leading to urine draining freely. Options A, B, and C are incorrect as they do not align with the physiological process and management of bladder exstrophy.
5. Which factors will the nurse consider when calculating the CURB-65 score for a patient with pneumonia? (Select one that does not apply)
- A. Age
- B. Blood pressure
- C. Respiratory rate
- D. Oxygen saturation
Correct answer: D
Rationale: The correct answer is 'Oxygen saturation.' When calculating the CURB-65 score for a patient with pneumonia, the factors considered include mental status (confusion), BUN (elevated), blood pressure (decreased), respiratory rate (increased), and age (65 and older). Oxygen saturation is not used in the CURB-65 scoring system. While blood pressure, respiratory rate, and age are factors that are used in the calculation of the CURB-65 score, oxygen saturation is not part of the scoring criteria. Therefore, oxygen saturation is the factor that does not apply when calculating the CURB-65 score.
