NCLEX RN Exam Review Answers
1. Based on Mr. C's assessment, which of the following nursing interventions is most appropriate?
- A. Elevate the lower extremities to 45 degrees to promote venous return
- B. Place Mr. C in the Trendelenburg position
- C. Administer total parenteral nutrition
- D. Monitor urine output
Correct answer: D
Rationale: In the context of Mr. C's assessment, the most appropriate nursing intervention is to monitor urine output. A client in hypovolemic shock may experience decreased urine output due to poor kidney perfusion. By monitoring urine output, the nurse can assess renal function and fluid status. Administering total parenteral nutrition (Choice C) is not indicated based on the information provided, as the priority is to stabilize the client's condition. Elevating the lower extremities (Choice A) may be helpful in some cases but is not the priority in this situation. Placing Mr. C in the Trendelenburg position (Choice B) is contraindicated in hypovolemic shock as it can worsen venous return and compromise cardiac output.
2. You are caring for Thomas N., a 77-year-old man with edema in his legs and a fluid restriction. You have been assigned to weigh him daily. Based on these symptoms and the care he is receiving, what disorder is he most likely affected by?
- A. Diabetes
- B. Dementia
- C. Congestive heart failure
- D. Contiguous heart disease
Correct answer: C
Rationale: Thomas N.'s symptoms of edema in his legs and fluid restriction point towards congestive heart failure (CHF) rather than dementia or diabetes. In CHF, patients often present with dependent edema in their legs due to excessive blood volume, leading to fluid intake restrictions and a low-salt diet. Daily weight monitoring is crucial in CHF to assess fluid retention or loss. Diabetes primarily affects blood sugar levels, dementia is a cognitive disorder, and 'Contiguous heart disease' is not a recognized medical term, making choices A, B, and D incorrect in this scenario.
3. A patient asks a nurse administering blood how long red blood cells live in the body. What is the correct response?
- A. The life span of RBC is 45 days
- B. The life span of RBC is 60 days
- C. The life span of RBC is 90 days
- D. The life span of RBC is 120 days
Correct answer: D
Rationale: The correct answer is that red blood cells have a lifespan of 120 days in the body. This allows for efficient oxygen transport throughout the circulatory system. Choices A, B, and C are incorrect because the lifespan of red blood cells is actually 120 days. Understanding the lifespan of red blood cells is crucial in assessing various conditions related to blood cell production and turnover.
4. When assessing a patient suspected to have Hepatitis, a nurse notes the patient's eyes are yellow-tinged. Which of the following diagnostic results would further assist in confirming this diagnosis?
- A. Decreased serum Bilirubin
- B. Elevated serum ALT levels
- C. Low RBC and Hemoglobin with increased WBCs
- D. Increased Blood Urea Nitrogen level
Correct answer: B
Rationale: Elevated serum ALT levels would further confirm the diagnosis of Hepatitis. ALT is a liver enzyme, and hepatitis is a liver disease. Elevated liver enzymes, such as ALT, often indicate liver damage. Choice A, 'Decreased serum Bilirubin,' is incorrect as elevated bilirubin levels are typically seen in hepatitis due to impaired bilirubin metabolism. Choices C and D are unrelated to confirming a diagnosis of hepatitis as they describe findings not specific to liver function or hepatitis. Low RBC and Hemoglobin with increased WBCs (Choice C) suggest a different condition like anemia or infection, not specific to liver disease. Increased Blood Urea Nitrogen level (Choice D) is more indicative of kidney function rather than liver function, thus not helpful in confirming hepatitis.
5. 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.
