Nursing Elites

1. 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.

2. The nurse assesses a patient suspected of having meningitis. Which of the following is a common clinical manifestation of this condition?

• A. A high WBC count and decreased level of consciousness
• B. A high WBC count and manic activity
• C. A low WBC count and manic activity
• D. A low WBC count and decreased level of consciousness

Correct answer: A

Rationale: The correct answer is 'A high WBC count and decreased level of consciousness.' Meningitis is often caused by an infectious organism, leading to an increase in Intracranial Pressure (ICP), which can result in decreased level of consciousness. While meningitis can trigger an inflammatory response, it typically presents with an elevated white blood cell (WBC) count rather than a low WBC count. Manic activity is not a common clinical manifestation of meningitis; instead, patients may exhibit altered mental status, confusion, or lethargy.

3. Why should a 30-year-old Caucasian woman who works the night shift take Vitamin D supplements?

• A. It's a standard part of the overall nutritional treatment for the prevention of osteomalacia.
• B. It helps your intestines absorb calcium, which is important for bone formation.
• C. It stimulates skin cells to produce calcium, which is then released into the bloodstream to be used for bone formation.
• D. Vitamin D supplements should not be taken by someone of your age.

Correct answer: B

Rationale: The correct answer is B: 'It helps your intestines absorb calcium, which is important for bone formation.' Vitamin D plays a crucial role in aiding the absorption of calcium from the intestines into the bloodstream, which is essential for bone health and formation. Choice A is incorrect because it does not specifically address the role of Vitamin D in calcium absorption. Choice C is incorrect as Vitamin D does not stimulate skin cells to produce calcium; rather, it helps regulate calcium levels in the body. Choice D is incorrect as age alone is not a contraindication for Vitamin D supplementation; the need for supplementation is based on individual health status and risk factors.

4. Which food should the assistive personnel be instructed to remove from the child's food tray based on the prescribed treatment for nephrotic syndrome?

• A. Pickle
• B. Wheat toast
• C. Baked chicken
• D. Steamed vegetables

Correct answer: A

Rationale: In nephrotic syndrome, a no-added-salt diet is recommended to manage the condition. High-sodium foods like pickles should be avoided as they can exacerbate fluid retention and swelling. Wheat toast, baked chicken, and steamed vegetables are generally suitable for individuals with nephrotic syndrome as they are low in sodium and protein, which are important considerations for this condition. Therefore, the correct choice is to remove the pickles from the child's food tray.

5. 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.
