Nursing Elites

1. A 20-year-old female attending college is found unconscious in her dorm room. She has a fever and a noticeable rash. She has just been admitted to the hospital. Which of the following tests is most likely to be performed first?

• A. Blood sugar check
• B. CT scan
• C. Blood cultures
• D. Arterial blood gases

Correct answer: C

Rationale: The most likely test to be performed first in this scenario is blood cultures. Blood cultures are crucial to investigate the fever and rash symptoms in an unconscious patient. This test is used to detect foreign invaders like bacteria, yeast, and other microorganisms in the blood, which could indicate a blood infection (bacteremia). A positive blood culture result confirms the presence of bacteria in the blood. A blood sugar check (choice A) may be important but is less likely to be the first test in this context. A CT scan (choice B) and arterial blood gases (choice D) are generally not the initial tests performed to investigate a fever and rash with altered mental status.

2. Which action should the nurse take to evaluate treatment effectiveness for a patient who has hepatic encephalopathy?

• A. Ask the patient to extend both arms forward.
• B. Request that the patient walk with eyes closed.
• C. Ask the patient to perform the Valsalva maneuver.
• D. Observe the patient's breathing pattern.

Correct answer: B

Rationale: To evaluate treatment effectiveness for a patient with hepatic encephalopathy, requesting the patient to walk with eyes closed is crucial. This test assesses the patient's balance, gait, and coordination, which can be impaired in hepatic encephalopathy due to altered mental status and brain function. Walking with eyes closed challenges the patient's sensory input and proprioception, providing valuable information on improvement or deterioration in neurological function. Asking the patient to extend both arms forward is used to check for asterixis, a sign often seen in hepatic encephalopathy, but it is not specific for evaluating treatment effectiveness. Performing the Valsalva maneuver is unrelated to assessing hepatic encephalopathy and is more commonly used in cardiac evaluations. Observing the patient's breathing pattern may be important in other conditions but is not directly relevant to evaluating treatment effectiveness for hepatic encephalopathy.

3. A patient is admitted with active tuberculosis (TB). The nurse should question a healthcare provider's order to discontinue airborne precautions unless which assessment finding is documented?

• A. Chest x-ray shows no upper lobe infiltrates.
• B. TB medications have been taken for 6 months.
• C. Mantoux testing shows an induration of 10 mm.
• D. Three sputum smears for acid-fast bacilli are negative.

Correct answer: D

Rationale: The correct answer is D: Three sputum smears for acid-fast bacilli are negative. Negative sputum smears indicate that Mycobacterium tuberculosis is not present in the sputum, and the patient cannot transmit the bacteria by the airborne route. This finding is crucial for discontinuing airborne precautions. Choice A is incorrect because chest x-rays do not determine the presence of active TB for transmission precautions. Choice B is not directly related to the infectiousness of TB; completing a 6-month course of medication is important for treatment but does not confirm the absence of active disease or infectiousness. Choice C is not relevant to assessing infectiousness; Mantoux testing measures exposure to TB but does not confirm the absence of active infection or infectiousness.

4. The clinic nurse reviews the record of an infant and notes that the primary health care provider (PHCP) has documented a diagnosis of suspected Hirschsprung's disease. The nurse reviews the assessment findings documented in the record, knowing that which sign most likely led the mother to seek health care for the infant?

• A. Diarrhea
• B. Projectile vomiting
• C. Regurgitation of feedings
• D. Constipation

Correct answer: C

Rationale: Hirschsprung's disease, also known as congenital aganglionosis or aganglionic megacolon, is characterized by the absence of ganglion cells in the rectum and other parts of the affected intestine. Clinical manifestations of Hirschsprung's disease include chronic constipation with pellet-like or ribbon-like foul-smelling stools, delayed or absent passage of meconium in the neonatal period, bowel obstruction (especially in the neonatal period), abdominal pain and distention, and failure to thrive. In the case of an infant with suspected Hirschsprung's disease, regurgitation of feedings is a sign that may have led the mother to seek healthcare. This symptom can be associated with the bowel dysfunction and obstruction seen in Hirschsprung's disease. Options A, B, and D are not typically associated with Hirschsprung's disease. Diarrhea is not a common symptom, projectile vomiting is not a typical presentation, and constipation, while a symptom of the disease, is not the sign that would most likely prompt a visit to seek healthcare in an infant suspected of having Hirschsprung's disease.

5. A patient is scheduled for a magnetic resonance imaging (MRI) scan for suspected lung cancer. Which of the following is a contraindication to the study for this patient?

• A. The patient is allergic to shellfish.
• B. The patient has a pacemaker.
• C. The patient suffers from claustrophobia.
• D. The patient takes antipsychotic medication.

Correct answer: B

Rationale: The correct answer is that the patient has a pacemaker. A pacemaker is a contraindication to MRI scanning due to the interference with the magnetic fields of the MRI scanner. This interference can potentially deactivate the pacemaker, putting the patient at risk. Patients with cardiac implantable electronic devices (CIED) are at risk for inappropriate device therapy, device heating/movement, and arrhythmia during MRI. This necessitates special precautions such as scheduling in a CIED blocked slot or having electrophysiology nurse or technician support. It is important to ensure that the patient's pacemaker is MRI conditional before proceeding with the scan. The other choices, such as being allergic to shellfish, suffering from claustrophobia, or taking antipsychotic medication, are not direct contraindications to undergoing an MRI scan for suspected lung cancer.
