Nursing Elites

1. 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.

2. After an unimmunized individual is exposed to hepatitis B through a needle-stick injury, which actions will the nurse plan to take (select one that does not apply)?

• A. Administer hepatitis B vaccine.
• B. Test for antibodies to hepatitis B.
• C. Teach about alpha-interferon therapy.
• D. Give hepatitis B immune globulin.

Correct answer: C

Rationale: In the case of exposure to hepatitis B, the nurse should plan to administer hepatitis B vaccine to provide active immunity. Testing for antibodies to hepatitis B is essential to determine the individual's immune status. Giving hepatitis B immune globulin is necessary for passive immunity in cases of exposure. However, teaching about alpha-interferon therapy is not part of the standard management for hepatitis B exposure. Interferon therapy and oral antivirals are typically used in the treatment of chronic hepatitis B infections, not for prophylaxis after exposure.

3. An older patient is receiving standard multidrug therapy for tuberculosis (TB). The nurse should notify the health care provider if the patient exhibits which finding?

• A. Yellow-tinged skin
• B. Orange-colored sputum
• C. Thickening of the fingernails
• D. Difficulty hearing high-pitched voices

Correct answer: A

Rationale: The correct answer is 'Yellow-tinged skin.' Yellow-tinged skin is indicative of noninfectious hepatitis, a toxic effect of isoniazid (INH), rifampin, and pyrazinamide. If a patient on TB therapy develops hepatotoxicity, alternative medications will be necessary. Thickening of fingernails and difficulty hearing high-pitched voices are not typical side effects of the medications used in standard TB therapy. Presbycusis, age-related hearing loss, is common in older adults and not a cause for immediate concern. Orange-colored sputum is an expected side effect of rifampin and does not warrant immediate notification to the healthcare provider.

4. The nurse is discussing negativism with the parents of a 30-month-old child. How should the nurse advise the parents to best respond to this behavior?

• A. Reprimand the child and give a 15-minute 'time out'
• B. Maintain a permissive attitude for this behavior
• C. Use patience and a sense of humor to deal with this behavior
• D. Assert authority over the child through limit setting

Correct answer: C

Rationale: Use patience and a sense of humor to deal with this behavior. The nurse should help the parents understand that negativism is a normal part of a toddler's growth towards autonomy. Reacting with patience and humor can help diffuse the situation and maintain a positive relationship with the child. Reprimanding the child and giving a 'time out' (Choice A) may not be effective for addressing negativism and can lead to power struggles. Maintaining a permissive attitude (Choice B) may reinforce negative behavior. Asserting authority through limit setting (Choice D) may be necessary in some situations, but using patience and humor is a more effective initial approach for handling negativism.

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.
