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. While auscultating a patient's lungs, the nurse hears low-pitched, bubbling sounds during inhalation in the lower third of both lungs. How should the nurse document this finding?

• A. Inspiratory crackles at the bases
• B. Expiratory wheezes in both lungs
• C. Abnormal lung sounds in the apices of both lungs
• D. Pleural friction rub in the right and left lower lobes

Correct answer: A

Rationale: The correct answer is 'Inspiratory crackles at the bases.' Crackles are low-pitched, bubbling sounds typically heard during inspiration, which aligns with the nurse's finding. Expiratory wheezes are high-pitched sounds and are not consistent with the described auscultation findings. The lower third of both lungs refers to the bases, not the apices, so option C is incorrect. Pleural friction rubs are grating sounds heard during both inspiration and expiration, unlike the described finding of only hearing the sounds during inhalation in the lower third of both lungs.

3. The parents of a newborn have been told that their child was born with bladder exstrophy, and the parents ask the nurse about this condition. Which explanation, given by the parents, indicates understanding of this condition?

• A. ''It's a hereditary disorder that occurs in every other generation.''
• B. ''It is caused by the use of medications taken by the mother during pregnancy.''
• C. ''It is a condition in which the urinary bladder is abnormally located in the pelvic cavity.''
• D. ''It's an extrusion of the urinary bladder to the outside of the body through a defect in the lower abdominal wall.''

Correct answer: D

Rationale: Bladder exstrophy is a congenital anomaly characterized by the extrusion of the urinary bladder to the outside of the body through a defect in the lower abdominal wall. The cause of bladder exstrophy is not precisely known, but it is believed to be due to a developmental abnormality during embryogenesis. The condition is more common in male newborns. Choice A is incorrect as bladder exstrophy is not a hereditary disorder that occurs in every other generation. Choice B is incorrect as bladder exstrophy is not caused by medications taken by the mother during pregnancy. Choice C is incorrect as it describes the condition inaccurately; it is not just an abnormal location of the bladder in the pelvic cavity, but rather an extrusion of the bladder outside the body through a defect in the lower abdominal wall.

4. A client with asthma has low-pitched wheezes present on the final half of exhalation. One hour later the client has high-pitched wheezes extending throughout exhalation. This change in assessment indicates to the nurse that the client

• A. Has increased airway obstruction
• B. Has improved airway obstruction
• C. Needs to be suctioned
• D. Exhibits hyperventilation

Correct answer: B

Rationale: The higher pitched a sound is, the more narrow the airway. Therefore, the obstruction has increased or worsened. With no evidence of secretions, there is no support to indicate the need for suctioning. Wheezes changing from low-pitched to high-pitched and extending throughout exhalation suggest a progression in airway constriction, indicating an increase in airway obstruction. Option B is incorrect because the change in wheezes from low to high pitch does not suggest an improvement in airway obstruction. Option C is incorrect as there is no indication of secretions requiring suctioning. Option D is incorrect as hyperventilation is not typically associated with the described change in wheezes.

5. A 49-year-old female patient with cirrhosis and esophageal varices has a new prescription for propranolol (Inderal). Which finding is the best indicator that the medication has been effective?

• A. The patient reports no chest pain.
• B. Blood pressure is 140/90 mm Hg
• C. Stools test negative for occult blood.
• D. The apical pulse rate is 68 beats/minute.

Correct answer: C

Rationale: The best indicator that propranolol has been effective in a patient with cirrhosis and esophageal varices is when the stools test negative for occult blood. Propranolol is prescribed to decrease the risk of bleeding from esophageal varices. This medication's effectiveness is primarily assessed by the absence of blood in the stools, indicating a reduction in the risk of bleeding from the varices. Monitoring for chest pain, blood pressure control, and a decrease in heart rate are important parameters in other conditions treated with propranolol, such as hypertension, angina, and tachycardia, but in this particular case, the absence of occult blood in the stools is the most relevant indicator of treatment success.
