The neurologist tests the 4th and 6th cranial nerves together by having a patient do which of the following?
- A. Turn his head to the right and left
- B. Say “ahhh”
- C. Identify whispering in his ears
- D. Follow his finger with his eyes
Correct Answer: D
Rationale: The correct answer is D because testing the 4th (trochlear) and 6th (abducens) cranial nerves involves assessing eye movements. The trochlear nerve controls downward and inward eye movement, while the abducens nerve controls lateral eye movement. Asking the patient to follow the finger with their eyes tests the function of both nerves simultaneously. Choices A, B, and C do not specifically target the 4th and 6th cranial nerves, making them incorrect options.

A nurse is directed to administer a hypotonic intravenous solution. The nurse expects that compensatory mechanisms associated with hypovolemia would cause all of the following symptoms except:
- A. O.45% sodium chloride
- B. 5% dextrose in water
- C. O.90% sodium chloride
- D. 5% dextrose in normal saline solution
Correct Answer: C
Rationale: The correct answer is C: 0.90% sodium chloride. When administering a hypotonic solution like 0.45% sodium chloride or 5% dextrose in water, water moves into the cells causing them to swell. This can exacerbate symptoms of hypovolemia such as low blood pressure and decreased perfusion. However, 0.90% sodium chloride is an isotonic solution and will not further exacerbate hypovolemic symptoms. Choices A, B, and D are hypotonic solutions that can worsen hypovolemic symptoms by causing cellular swelling.
Which action indicates a nurse is using critical thinking for implementation of nursing care to patients?
- A. Determines whether an intervention is correct and appropriate for the given situation
- B. Reads over the steps and performs a procedure despite lack of clinical competency
- C. Establishes goals for a particular patient without assessment
- D. Evaluates the effectiveness of interventions
Correct Answer: A
Rationale: The correct answer is A because determining whether an intervention is correct and appropriate for the given situation indicates critical thinking in nursing care implementation. This involves assessing the patient's needs, analyzing the situation, and using evidence-based practice to make informed decisions. This process ensures that interventions are tailored to individual patient needs and promotes safe and effective care delivery.
Option B is incorrect because performing a procedure without clinical competency can jeopardize patient safety and is not an example of critical thinking. Option C is incorrect as establishing goals without assessment lacks a foundation in data and may lead to inappropriate care planning. Option D is incorrect as evaluating the effectiveness of interventions is a part of the nursing process but does not specifically demonstrate critical thinking in implementation.
The nurse is reviewing a patient’s plan of care, which includes the nursing diagnostic statement, Impaired physical mobility related to tibial fracture as evidenced by patient’s inability to ambulate. Which part of the diagnostic statement does the nurse need to revise?
- A. Etiology
- B. Nursing diagnosis
- C. Collaborative problem
- D. Defining characteristic
Correct Answer: C
Rationale: The correct answer is C: Collaborative problem. The nurse needs to revise this part of the diagnostic statement because impaired physical mobility related to tibial fracture is a nursing diagnosis, not a collaborative problem. Collaborative problems are issues that require both medical and nursing interventions, whereas nursing diagnoses are within the scope of nursing practice. The etiology identifies the cause of the problem (tibial fracture), the nursing diagnosis states the problem (impaired physical mobility), and the defining characteristic is the evidence that supports the diagnosis (inability to ambulate). Therefore, the nurse should revise the part stating collaborative problem as it does not align with the nature of the issue presented in the scenario.
Why is heart biopsy performed throughout a clients lifetime after heart transplantation?
- A. To detect rejection
- B. To check the heart functionality
- C. To check rate of the heartbeat
- D. To check for heart tumor CARING FOR CLIENTS WITH HYPERTENSION
Correct Answer: A
Rationale: The correct answer is A: To detect rejection. After heart transplantation, heart biopsy is performed to monitor for rejection, a common complication. Tissue samples are examined for signs of rejection, such as inflammation. This is crucial for timely intervention to prevent rejection-related complications.
Other choices are incorrect:
B: Heart functionality is typically assessed through imaging tests like echocardiograms, not biopsy.
C: Heart rate monitoring can be done through non-invasive methods like electrocardiograms, not biopsy.
D: Checking for heart tumors is not a primary purpose of heart biopsy post-transplantation.
The nurse encourages a client with an immunologic disorder to eat a nutritionally balanced diet to promote optimal immunologic function. Autoimmunity has been linked to excessive ingestion of:
- A. Protein
- B. Vitamin A
- C. Fat
- D. Zinc
Correct Answer: C
Rationale: The correct answer is C: Fat. Excessive ingestion of fat has been linked to autoimmunity due to its potential to trigger inflammation in the body, which can disrupt the immune system's balance and lead to autoimmune responses. High-fat diets have been associated with increased production of pro-inflammatory molecules, impacting immune function negatively. Protein (choice A) is essential for immune function, vitamin A (choice B) supports immune responses, and zinc (choice D) is crucial for immune system regulation. However, excessive intake of these nutrients typically does not directly lead to autoimmunity like excessive fat consumption does.
