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.

The majority of lumbar disc herniations occur at the level of:
- A. L1 –L2
- B. L4-L5
- C. L3-L4
- D. S1-S2
Correct Answer: B
Rationale: The correct answer is B: L4-L5. This is because the L4-L5 intervertebral disc segment experiences the highest amount of mechanical stress and mobility in the lumbar spine, making it more prone to herniation. Additionally, nerve roots at this level innervate the lower extremities, making it a common site for symptoms such as sciatica. Choices A, C, and D are incorrect because herniations at those levels are less common due to lower mechanical stress and mobility compared to L4-L5.
Wilma is using a portable suction unit at home, What is the amount of suction required by James using this unit?
- A. 2-5 mmHg
- B. 10-15 mmHg
- C. 5-10 mmHg
- D. 20-25 mmHg
Correct Answer: B
Rationale: The correct answer is B (10-15 mmHg) because this range is considered safe and effective for suctioning in most cases. Lower suction pressures (such as 2-5 mmHg) may not effectively clear secretions, while higher pressures (20-25 mmHg) can cause tissue damage. Choice C (5-10 mmHg) falls within the safe range but may not provide enough suction for effective clearance. Therefore, the optimal suction pressure for James using the portable suction unit at home is 10-15 mmHg.
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 the collaborative problem part of the diagnostic statement because "Impaired physical mobility related to tibial fracture as evidenced by patient’s inability to ambulate" is a nursing diagnosis, not a collaborative problem. Collaborative problems involve issues that require both nursing and medical interventions, whereas nursing diagnoses focus on the nurse's role in addressing the patient's health issues. Therefore, the nurse should revise the collaborative problem part to accurately reflect the collaborative aspect of the patient's care. Etiology (A), nursing diagnosis (B), and defining characteristic (D) are not the parts of the diagnostic statement that need revision in this scenario.
Mrs. Santos, a 75-year old patient with type II diabetes is in emergency department with signs of hyperglycemic, hyperosmolar nonketotic (HHNK) coma. What assessment finding should the nurse expect?
- A. Fruity odor of the breath
- B. shallow, deep respirations
- C. severe dehydration
- D. profuse sweating
Correct Answer: C
Rationale: The correct answer is C: severe dehydration. In HHNK coma, the body tries to eliminate excess glucose through frequent urination, leading to dehydration. This results in decreased blood volume, causing hypotension and tachycardia. Signs include dry mucous membranes, poor skin turgor, and concentrated urine output. Fruity odor of the breath (A) is associated with diabetic ketoacidosis, not HHNK coma. Shallow, deep respirations (B) and profuse sweating (D) are not typically associated with HHNK coma.
The presence of anemia is characterized by a/an:
- A. Increase of red blood cells
- B. Increased hemoglobin
- C. Decrease in the concentration of red blood
- D. Decreased blood count cells
Correct Answer: C
Rationale: Step-by-step rationale:
1. Anemia is a condition where there is a decrease in the concentration of red blood cells.
2. Red blood cells carry oxygen to the body's tissues, so a decrease in their concentration leads to reduced oxygen delivery.
3. This decrease in red blood cell concentration can be measured through a decrease in hematocrit levels.
4. Choices A and B are incorrect because anemia involves a decrease, not an increase, in red blood cells and hemoglobin.
5. Choice D is incorrect as it mentions "decreased blood count cells," which is not a specific term related to anemia.
Summary: The correct answer is C because anemia is characterized by a decrease in the concentration of red blood cells, leading to reduced oxygen delivery, while the other choices are incorrect due to inaccuracies in describing anemia.
