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. A client complained of nausea, a metallic taste in her mouth, and fine hand tremors 2 hours after her first dose of lithium carbonate (Lithane). What is the nurse's best explanation of these findings?

• A. These side effects are common and should subside in a few days.
• B. The client is probably having an allergic reaction and should discontinue the drug.
• C. Taking the lithium on an empty stomach should decrease these symptoms.
• D. Decreasing dietary intake of sodium and fluids should minimize the side effects.

Correct answer: A

Rationale: The correct answer is, 'These side effects are common and should subside in a few days.' Nausea, metallic taste, and fine hand tremors are common side effects of lithium carbonate (Lithane) and typically diminish within a few days as the body adjusts to the medication. Option B is incorrect because these symptoms are not indicative of an allergic reaction. Option C is incorrect as taking lithium on an empty stomach does not directly address or decrease these specific side effects. Option D is also incorrect as reducing sodium and fluid intake is not the recommended approach to managing these particular side effects of lithium.

3. The nurse provides discharge instructions to a patient who was hospitalized for pneumonia. Which statement, if made by the patient, indicates a good understanding of the instructions?

• A. I will call the doctor if I still feel tired after a week.
• B. I will continue to do the deep breathing and coughing exercises at home.
• C. I will continue to do the deep breathing and coughing exercises at home.
• D. I'll cancel my chest x-ray appointment if Im feeling better in a couple weeks

Correct answer: C

Rationale: Patients should continue to cough and deep breathe after discharge. Fatigue is expected for several weeks. The Pneumovax and influenza vaccines can be given at the same time in different arms. Explain that a follow-up chest x-ray needs to be done in 6 to 8 weeks to evaluate resolution of pneumonia.

4. When assessing a child admitted to the hospital with pyloric stenosis, which symptom would the nurse likely find when asking the parent about the child's symptoms?

• A. Watery diarrhea
• B. Projectile vomiting
• C. Increased urine output
• D. Vomiting large amounts of bile

Correct answer: B

Rationale: In pyloric stenosis, hypertrophy of the circular muscles of the pylorus causes narrowing of the pyloric canal between the stomach and the duodenum. The hallmark symptom of pyloric stenosis is projectile vomiting, which is the forceful expulsion of stomach contents. Other common symptoms include irritability, hunger and crying, constipation, and signs of dehydration. Watery diarrhea (Choice A) is not a typical symptom of pyloric stenosis. Increased urine output (Choice C) is not directly associated with this condition. Vomiting large amounts of bile (Choice D) is not a characteristic symptom of pyloric stenosis; instead, the vomitus in pyloric stenosis is non-bilious.

5. Which of the following glands found in the skin secretes a liquid called Sebum?

• A. Apocrine Glands
• B. Sebaceous Glands
• C. Lacrimal Glands
• D. Sweat Glands

Correct answer: B

Rationale: Sebum is a liquid secreted by glands in the skin known as sebaceous glands. Sebum's primary function is to lubricate the skin and help maintain its integrity. Apocrine glands secrete a different type of sweat that is odorless but can develop an odor when combined with bacteria on the skin. Lacrimal glands produce tears to keep the eyes moist, and sweat glands secrete sweat to regulate body temperature through evaporation. Therefore, the correct answer is Sebaceous Glands because they specifically secrete sebum, distinguishing them from the other gland types mentioned.
