Nursing Elites

1. What is the main function of the mitochondria in a cell?

• A. To produce energy in the form of ATP
• B. To synthesize proteins
• C. To store genetic information
• D. To regulate cell growth

Correct answer: A

Rationale: The correct answer is A: To produce energy in the form of ATP. Mitochondria are known as the powerhouse of the cell because they are responsible for producing energy in the form of ATP through a process called cellular respiration. This energy is essential for various cellular activities. Choice B is incorrect because protein synthesis primarily occurs in the ribosomes. Choice C is incorrect as the genetic information is stored in the cell's nucleus. Choice D is incorrect as the regulation of cell growth involves various other organelles and processes within the cell.

2. A female patient is concerned about the side effects of hormone replacement therapy (HRT). What common side effect should the nurse explain?

• A. Weight gain
• B. Hair loss
• C. Increased libido
• D. Decreased energy levels

Correct answer: A

Rationale: The correct answer is A: Weight gain. Weight gain is a common side effect of hormone replacement therapy (HRT) due to hormonal changes. Patients should be informed about this possibility as part of their treatment plan. Hair loss (Choice B) is not a common side effect of HRT. Increased libido (Choice C) and decreased energy levels (Choice D) are not typically associated with HRT side effects. Therefore, the nurse should focus on discussing weight gain with the patient.

3. A client with a history of rheumatic fever presents with signs of heart failure. What is the likely underlying cause?

• A. Infective endocarditis
• B. Coronary artery disease
• C. Mitral valve stenosis
• D. Aortic regurgitation

Correct answer: C

Rationale: The correct answer is C: Mitral valve stenosis. Rheumatic fever can lead to scarring and thickening of the heart valves, often affecting the mitral valve. This stenosis can impede blood flow from the left atrium to the left ventricle, eventually causing heart failure. Choice A, infective endocarditis, is an infection of the endocardium, the inner lining of the heart chambers and valves, and is not directly related to rheumatic fever. Choice B, coronary artery disease, involves the obstruction of coronary arteries supplying the heart muscle with blood, leading to ischemia and not typically associated with rheumatic fever. Choice D, aortic regurgitation, is the backflow of blood from the aorta to the left ventricle and is not a common consequence of rheumatic fever.

4. A client with Guillain-Barré syndrome is experiencing ascending paralysis. Which of the following interventions should the nurse prioritize?

• A. Monitor for signs of respiratory distress.
• B. Prepare the client for plasmapheresis.
• C. Administer analgesics for pain management.
• D. Initiate passive range-of-motion exercises.

Correct answer: A

Rationale: The correct answer is A: Monitor for signs of respiratory distress. In Guillain-Barré syndrome, ascending paralysis can lead to respiratory muscle involvement, putting the client at risk for respiratory distress and failure. Prioritizing respiratory monitoring is crucial to ensure timely intervention if respiratory compromise occurs. Plasmapheresis (Choice B) may be indicated in some cases to remove harmful antibodies, but the priority in this situation is respiratory support. Administering analgesics (Choice C) for pain management and initiating passive range-of-motion exercises (Choice D) are important aspects of care but are not the priority when the client's respiratory status is at risk.

5. A 60-year-old man presents with painless hematuria. Which of the following should be the next step in the evaluation?

• A. Urinalysis
• B. Renal ultrasound
• C. Cystoscopy
• D. Intravenous pyelogram

Correct answer: C

Rationale: In a 60-year-old man presenting with painless hematuria, the next step in the evaluation should be cystoscopy. Cystoscopy is recommended to assess the cause of hematuria, particularly to rule out bladder cancer, which is more common in older individuals. Urinalysis (Choice A) can provide initial information but may not definitively diagnose the underlying cause. Renal ultrasound (Choice B) and intravenous pyelogram (Choice D) are imaging studies that may be considered later in the evaluation process but are not the initial step for painless hematuria.
