Nursing Elites

1. 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.

2. 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.

3. A patient with severe mitral regurgitation and decreased cardiac output is being cared for by a nurse. The nurse assesses the patient for mental status changes. What is the rationale for this intervention?

• A. Decreased cardiac output can cause hypoxia to the brain
• B. Mental status changes may be a side effect of the patient's medication
• C. Mitral regurgitation is a complication associated with some neurological disorders
• D. The patient may be confused about his diagnosis

Correct answer: A

Rationale: When caring for a patient with severe mitral regurgitation and decreased cardiac output, assessing for mental status changes is crucial. Decreased cardiac output can lead to inadequate perfusion and oxygenation of vital organs, including the brain, resulting in hypoxia. This hypoxia can manifest as mental status changes such as confusion, restlessness, or lethargy. Therefore, monitoring mental status helps in identifying potential hypoxic states and guiding appropriate interventions. The other options are incorrect as they do not directly correlate decreased cardiac output with potential hypoxia-induced mental status changes.

4. Why are subdural hemorrhages more common in the elderly?

• A. Increased anticoagulant use
• B. Increased risk of falls
• C. Brain atrophy
• D. Inconsistent care giving

Correct answer: C

Rationale: Subdural hemorrhages are more common in the elderly due to cerebral atrophy resulting from the natural aging process. This atrophy can lead to the stretching of bridging veins, making them more fragile and prone to tearing even with minor trauma. While increased anticoagulant use and a higher risk of falls are common in the elderly, brain atrophy plays a more direct role in the increased incidence of subdural hemorrhages. Inconsistent caregiving, on the other hand, is not a direct cause of subdural hemorrhages but may impact the overall management and outcome of such cases.

5. A mother brings her 5-week-old infant to the health care clinic and tells the nurse that the child has been vomiting after meals. The mother reports that the vomiting is becoming more frequent and forceful. The nurse suspects pyloric stenosis and asks the mother which assessment question to elicit data specific to this condition?

• A. Are the stools ribbon-like, and is the infant eating poorly?
• B. Does the infant suddenly become pale, begin to cry, and draw the legs up to the chest?
• C. Does the vomit contain sour, undigested food without bile, and is the infant constipated?
• D. Does the infant cry loudly and continuously during the evening hours but nurses or takes formula well?

Correct answer: C

Rationale: Vomiting undigested food that is not bile stained and constipation are classic symptoms of pyloric stenosis. Stools that are ribbon-like and a child who is eating poorly are signs of congenital megacolon (Hirschsprung's disease). An infant who suddenly becomes pale, cries out, and draws the legs up to the chest is demonstrating physical signs of intussusception. Crying during the evening hours, appearing to be in pain, eating well, and gaining weight are clinical manifestations of colic.
