NCLEX RN Exam Review Answers
1. A nursing student caring for a 6-month-old infant is asked to collect a sample for urinalysis from the infant. How should the student collect the specimen?
- A. Catheterizing the infant using the smallest available Foley catheter
- B. Attaching a urinary collection device to the infant's perineum for collection
- C. Obtaining the specimen from the diaper by squeezing the diaper after the infant voids
- D. Noting the time of the next expected voiding and then preparing a specimen cup for the urine
Correct answer: B
Rationale: The correct method for collecting a urine sample from an infant for urinalysis is by attaching a urinary collection device to the infant's perineum. This device is a plastic bag with an adhesive opening that allows it to be secured to the perineum to collect urine. Catheterizing the infant with a Foley catheter should not be done unless specifically prescribed due to the risk of infection. Obtaining the specimen from the diaper by squeezing it after the infant voids may not provide an accurate sample for urinalysis. Trying to predict the time of the next voiding to prepare a specimen cup is not practical or reliable in ensuring an appropriate sample for urinalysis.
2. A client is scheduled for a percutaneous transluminal coronary angioplasty (PTCA). The nurse knows that a PTCA is
- A. Surgical repair of a diseased coronary artery.
- B. Placement of an automatic internal cardiac defibrillator.
- C. Procedure that compresses plaque against the wall of the diseased coronary artery to improve blood flow.
- D. Non-invasive radiographic examination of the heart.
Correct answer: C
Rationale: Percutaneous transluminal coronary angioplasty (PTCA) is a procedure that involves compressing plaque against the wall of a diseased coronary artery to improve blood flow. It is a minimally invasive procedure performed during a cardiac catheterization to open blockages in the coronary arteries. Surgical repair of a diseased coronary artery refers to procedures like coronary artery bypass grafting (CABG), not PTCA. Placement of an automatic internal cardiac defibrillator is a different intervention used for managing cardiac arrhythmias, not for improving coronary blood flow. A non-invasive radiographic examination of the heart would typically refer to procedures like a cardiac CT scan or an MRI, not PTCA.
3. A patient is being admitted to the ICU with a severe case of encephalitis. Which of these drugs would the nurse not expect to be prescribed for this condition?
- A. Acyclovir (Zovirax)
- B. Mannitol (Osmitrol)
- C. Lactated Ringer's
- D. Phenytoin (Dilantin)
Correct answer: C
Rationale: In the treatment of encephalitis, medications like Acyclovir and Phenytoin are commonly prescribed. Acyclovir is an antiviral medication used to treat viral infections like herpes simplex virus, which can cause encephalitis. Phenytoin is an antiepileptic drug that may be used to manage seizures associated with encephalitis. Mannitol is a diuretic used to reduce intracranial pressure (ICP) by decreasing cerebral edema. Lactated Ringer's solution, on the other hand, is primarily used in fluid replacement therapy and may not be indicated if a patient is at risk for high ICP, as excessive fluid administration could worsen cerebral edema and increase ICP.
4. A nurse frequently treats patients in the 72-hour period after a stroke has occurred. The nurse would be most concerned about which of these assessment findings?
- A. INR is 3 seconds long
- B. Heart rate is 110 beats per minute
- C. Intracranial Pressure is 22 mmHg
- D. Blood pressure is 140/80
Correct answer: C
Rationale: The nurse would be most concerned about the assessment finding of an Intracranial Pressure (ICP) reading of 22 mmHg in a patient 72 hours post-stroke. Elevated ICP can indicate increased risk of edema and further brain damage. A target ICP should ideally be maintained at less than or equal to 15-20 mmHg. While the other options may also be important to monitor, an elevated ICP poses a more immediate threat to the patient's neurological status and requires prompt attention.
5. The nurse is performing tuberculosis (TB) skin tests in a clinic that has many patients who have immigrated to the United States. Which question is most important for the nurse to ask before the skin test?
- A. Is there any family history of TB?
- B. How long have you lived in the United States?
- C. Do you take any over-the-counter (OTC) medications?
- D. Have you received the bacille Calmette-Guerin (BCG) vaccine for TB?
Correct answer: D
Rationale: It is crucial for the nurse to inquire about whether the patient has received the bacille Calmette-Guerin (BCG) vaccine for TB before performing the skin test. Patients who have received the BCG vaccine can have a positive Mantoux test, leading to the need for alternative screening methods, such as a chest x-ray, to determine TB infection. While family history of TB and length of time in the United States are relevant factors, they do not directly impact the decision to perform the TB skin test. Asking about over-the-counter medications, unless relevant to TB treatment, is not as critical as assessing BCG vaccination status.
