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.

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.
Which of the following nursing actions is appropriate when a patient returns to his or her room after a bronchoscopy?
- A. Order a meal because the patient has been nil per os (NPO) for 8 hours.
- B. Encourage fluids to flush dye from the patient’s system.
- C. Monitor the patient for return to consciousness.
- D. Check for a gag reflex before allowing the patient to drink.
Correct Answer: D
Rationale: The correct answer is D - Check for a gag reflex before allowing the patient to drink. This is important after a bronchoscopy to prevent aspiration. Step 1: Assessing gag reflex ensures the patient can protect their airway. Step 2: Aspiration risk is high post-bronchoscopy due to sedation and possible throat numbness. Step 3: Allowing fluids without confirming gag reflex can lead to aspiration pneumonia. Other choices are incorrect. A: Ordering a meal immediately is inappropriate after NPO period. B: Encouraging fluids without assessing gag reflex may lead to aspiration. C: Monitoring consciousness is important but not directly related to post-bronchoscopy care.
The Glasgow coma scale is used to .evaluate the level of consciousness in the neurological and neurological patients. The three assessment factors included in this scale are:
- A. pupil size, response to pain, motor responses
- B. Pupil size, verbal response, motor response
- C. Eye opening, verbal response, motor response
- D. Eye opening, response to pain, motor response J.E, is an 18-year old freshman admitted to the ICU following a motor vehicle accident in which he sustained multiple trauma including a ruptured spleen, myocardial contusion, fractured pelvis, and fractured right femur. He had a mild contusion, but is alert and oriented. His vital signs BP 120/80, pulse 84, respirations 12, and temperature 99 F orally.
Correct Answer: C
Rationale: The correct answer is C: Eye opening, verbal response, motor response. The Glasgow Coma Scale (GCS) assesses the level of consciousness by evaluating these three factors. Eye opening assesses the patient's ability to open their eyes spontaneously or in response to stimuli. Verbal response evaluates the patient's ability to speak or respond to verbal stimuli. Motor response assesses the patient's motor function by testing responses to commands or painful stimuli. Choice A is incorrect because it includes "response to pain" instead of "verbal response." Choice B is incorrect because it includes "verbal response" instead of "eye opening." Choice D is incorrect because it includes "eye opening" instead of "verbal response." In summary, the GCS evaluates eye opening, verbal response, and motor response to determine the level of consciousness in patients.
Which of the following nursing interventions is correctly categorized as collaborative?
- A. Administering medications as prescribed by the healthcare provider
- B. Ordering a low-sodium diet for a hypertensive client
- C. Providing health education about medication side effects
- D. Monitoring a client’s response to an intervention initiated by another healthcare professional
Correct Answer: D
Rationale: The correct answer is D because monitoring a client's response to an intervention initiated by another healthcare professional is a collaborative nursing intervention. This involves working together with other healthcare team members to assess the client's progress and adjust care as needed. It promotes continuity of care and ensures that the client's needs are met effectively.
A: Administering medications is typically an independent nursing intervention.
B: Ordering a low-sodium diet is within the scope of a nurse's independent practice.
C: Providing health education is often considered an independent nursing intervention unless it involves collaboration with other team members.
In summary, choice D is the correct answer as it exemplifies collaborative care within a healthcare team.
A patient is being given Digoxin to treat heart failure. Which of the ff. is a usual adult daily dosage of digoxin (Lanoxin)?
- A. 0.005 mg
- B. 0.025 mg
- C. 0.25 mg
- D. 2.5 mg
Correct Answer: C
Rationale: Rationale:
C: 0.25 mg is the correct daily dosage of Digoxin for adults with heart failure. This dosage is within the usual range of 0.125-0.25 mg. It helps improve heart function and manage heart failure symptoms.
A: 0.005 mg is too low and ineffective.
B: 0.025 mg is also too low for therapeutic effect.
D: 2.5 mg is too high and may lead to toxicity in most adult patients.
