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?

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 thirty-five-year-old male has been an insulin-dependent diabetic for five years and now is unable to urinate. Which of the following would you most likely suspect?

Correct answer: C

Rationale: In this case, the correct answer is autonomic neuropathy. Autonomic neuropathy affects the autonomic nerves, which control various bodily functions including the bladder. In diabetes, it can lead to bladder paralysis, resulting in symptoms like urgency to urinate and difficulty initiating urination. Atherosclerosis (choice A) is a condition involving the hardening and narrowing of arteries, not directly related to the inability to urinate in this context. Diabetic nephropathy (choice B) primarily affects the kidneys, leading to kidney damage, but does not typically cause urinary retention. Somatic neuropathy (choice D) involves damage to sensory nerves, not the autonomic nerves responsible for bladder control, making it less likely to be the cause of the urinary issue described in the question.

3. A nurse is caring for a patient after a coronary angiogram. Which of these actions taken by the nursing assistant would most require the nurse's immediate intervention?

Correct answer: B

Rationale: After a coronary angiogram, patients need to maintain bed rest and keep the head of the bed at no more than 30 degrees for 3-6 hours, depending on the insertion site. Elevating the head of the bed to 60 degrees for a meal could increase the risk of bleeding or complications at the insertion site. Refilling the ice pack placed on the insertion site is appropriate for managing potential swelling or discomfort. Filling the patient's pitcher with ice-cold drinking water is a standard care task. Placing an extra pillow under the patient's head upon request is a comfort measure and does not pose a risk to the patient's recovery.

4. The nurse is caring for a 27-year-old female client with a venous stasis ulcer. Which nursing intervention would be most effective in promoting healing?

Correct answer: B

Rationale: Venous stasis occurs when venous blood collects and stagnates in the lower leg due to incompetent venous valves. This leads to inadequate oxygen and nutrient supply to the cells in the lower extremities, resulting in cell death or necrosis. Venous stasis ulcers, characterized by shallow brown wounds with irregular margins, typically develop on the lower leg or ankle. The primary goal in managing clients with venous stasis ulcers is to promote healing. Proper nutrition plays a crucial role in wound healing. Nutritional deficiencies are common causes of venous ulcers, and a diet rich in protein, iron, zinc, and vitamins C and A is recommended to enhance wound healing. Applying dressings with sterile technique, initiating limb compression therapy, and beginning proteolytic debridement are important interventions in wound care but may not directly address the underlying issue of poor nutrition that is essential for healing venous stasis ulcers.

5. A 20-year-old female attending college is found unconscious in her dorm room. She has a fever and a noticeable rash. She has just been admitted to the hospital. Which of the following tests is most likely to be performed first?

Correct answer: C

Rationale: The most likely test to be performed first in this scenario is blood cultures. Blood cultures are crucial to investigate the fever and rash symptoms in an unconscious patient. This test is used to detect foreign invaders like bacteria, yeast, and other microorganisms in the blood, which could indicate a blood infection (bacteremia). A positive blood culture result confirms the presence of bacteria in the blood. A blood sugar check (choice A) may be important but is less likely to be the first test in this context. A CT scan (choice B) and arterial blood gases (choice D) are generally not the initial tests performed to investigate a fever and rash with altered mental status.
