Nursing Elites

1. When teaching the client with tuberculosis about follow-up home care, the nurse should emphasize that a laboratory appointment for which of the following lab tests is critical?

• A. Liver function
• B. Kidney function
• C. Blood sugar
• D. Cardiac enzymes

Correct answer: A

Rationale: The nurse should emphasize the importance of monitoring liver function tests in clients taking INH due to the risk of hepatocellular injury and hepatitis associated with this medication. Regular assessment of liver enzymes can help detect liver damage early. Monitoring kidney function, blood sugar levels, or cardiac enzymes is not specifically required for clients taking INH and tuberculosis treatment.

2. A child is diagnosed with Hirschsprung's disease. The nurse is teaching the parents about the cause of the disease. Which statement, if made by the parent, supports that teaching was successful?

• A. The absence of special cells in the rectum caused the disease.
• B. Incomplete digestion of the protein part of wheat, barley, rye, and oats is not the cause of the disease.
• C. The disease does not occur due to increased bowel motility leading to spasm and pain.
• D. The disease is not caused by the inability to tolerate sugar found in dairy products.

Correct answer: A

Rationale: Hirschsprung's disease, also known as congenital aganglionosis or megacolon, is characterized by the absence of ganglion cells in the rectum and, sometimes, extending into the colon. Choice A correctly explains the cause of Hirschsprung's disease. Choice B is incorrect as it describes celiac disease, which is related to gluten intolerance. Choice C is inaccurate as it describes symptoms of irritable bowel syndrome, not the cause of Hirschsprung's disease. Choice D is wrong as it pertains to lactose intolerance, not Hirschsprung's disease.

3. 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.

4. A patient is undergoing a stress test on a treadmill and turns to talk to the nurse. Which of these statements would require the most immediate intervention?

• A. I'm feeling extremely thirsty and will get some water after this.
• B. I can feel my heart racing.
• C. My shoulder and arm are hurting.
• D. My blood pressure reading is 158/80

Correct answer: C

Rationale: The correct answer is 'C: My shoulder and arm are hurting.' Unilateral arm and shoulder pain are classic symptoms of myocardial ischemia, indicating possible heart issues. In this scenario, immediate intervention is required, and the stress test should be halted. Choice A about feeling thirsty does not indicate an acute medical issue. Choice B mentioning heart racing is expected during a stress test. Choice D, a blood pressure reading of 158/80, while slightly elevated, does not present an immediate concern compared to the symptoms of arm and shoulder pain suggesting cardiac distress.

5. A 15-year-old female who ingested 15 tablets of maximum strength acetaminophen 45 minutes ago is rushed to the emergency department. Which of these orders should the nurse do first?

• A. Gastric lavage
• B. Administer acetylcysteine (Mucomyst) orally
• C. Start an IV Dextrose 5% with 0.33% normal saline to keep the vein open
• D. Have the patient drink activated charcoal mixed with water

Correct answer: A

Rationale: Acetaminophen overdose is extremely toxic to the liver causing hepatotoxicity. Early symptoms of hepatic damage include nausea, vomiting, abdominal pain, and diarrhea. If not treated immediately, hepatic necrosis occurs and may lead to death. Removing as much of the drug as possible is the first step in treatment for acetaminophen overdose, this is best done through gastric lavage. Gastric lavage (irrigation) and aspiration consist of flushing the stomach with fluids and then aspirating the fluid back out. This procedure is done in life-threatening cases such as acetaminophen toxicity and only if less than one (1) hour has occurred after ingestion.
