Nokea
A nurse is collecting data as part of a neurological examination of a client who is receiving treatment for head trauma. Which of the following observations will give the nurse information about the function of the third cranial nerve?
- A. Instruct the client to look up and down without moving his head.
- B. Observe the client's ability to smile and frown.
- C. Evaluate the client's pupillary reaction to light.
- D. Ask the client to shrug his shoulders against passive resistance.
Correct Answer: C
Rationale: The correct answer is C: Evaluate the client's pupillary reaction to light. The third cranial nerve, also known as the oculomotor nerve, controls the pupillary response by constricting the pupil when exposed to light. By observing the client's pupillary reaction to light, the nurse can assess the function of the third cranial nerve. This test specifically targets the parasympathetic fibers of the nerve, which control pupillary constriction.
Choice A (Instruct the client to look up and down without moving his head) would assess the function of the fourth cranial nerve (trochlear nerve).
Choice B (Observe the client's ability to smile and frown) would assess the function of the seventh cranial nerve (facial nerve).
Choice D (Ask the client to shrug his shoulders against passive resistance) would assess the function of the eleventh cranial nerve (accessory nerve).
Therefore, choices A, B, and D are

A nurse is measuring an adult client's tympanic temperature. Which of the following actions should the nurse take?
- A. Use a cotton-tipped applicator to remove cerumen.
- B. Pull the pinna downward and backward.
- C. Aim the probe posteriorly in the direction of the eardrum.
- D. Insert the probe with a circular motion.
Correct Answer: C
Rationale: The correct answer is C because aiming the probe posteriorly in the direction of the eardrum allows for accurate tympanic temperature measurement. This ensures that the infrared sensor is positioned correctly to capture the heat emitted from the tympanic membrane. Choice A is incorrect as removing cerumen is not necessary for temperature measurement. Choice B is incorrect as pulling the pinna downward and backward is not required for tympanic temperature measurement. Choice D is incorrect as inserting the probe with a circular motion may cause discomfort or injury to the ear canal.
A nurse is assisting with the readmission of a client to the medical unit after a transfer to ICU following a suicide attempt using an overdose of medication. The client looks down at the floor and mumbles, 'Hello.' Which of the following responses should the nurse make?
- A. You have been transferred back to this unit. This is your new room.
- B. Hello. I see that in ICU you've been getting a light diet. How does your stomach feel now?
- C. I was upset when I found you had tried to kill yourself.
- D. Would you like to talk about what happened?
Correct Answer: D
Rationale: Encouraging open communication provides emotional support and helps the client process their feelings.
Which of the following should the nurse recognize as a sign of possible infection in a postoperative client? (Select all that apply.)
- A. Increased urine output
- B. Adventitious breath sounds
- C. Decreased level of consciousness
- D. Dry crust on the incision line
- E. Oral temperature of 38.3°C (101°F)
Correct Answer: B,C,E
Rationale: Adventitious breath sounds suggest pneumonia, decreased consciousness may indicate sepsis, and fever is a systemic infection response. Increased urine output is not a sign, and dry crust is part of normal healing.
A nurse is collecting data from the mother of a toddler. Which of the following activities should the nurse expect the toddler to be able to perform?
- A. Jump rope
- B. Ride a tricycle
- C. Print letters and numbers
- D. Use scissors to cut out a picture
Correct Answer: B
Rationale: The correct answer is B: Ride a tricycle. Toddlers typically develop the coordination and balance needed to ride a tricycle around the age of 3. This activity helps improve gross motor skills and coordination. Jumping rope (A) requires more advanced motor skills and coordination. Printing letters and numbers (C) involves fine motor skills that develop later. Using scissors to cut out a picture (D) also requires more advanced fine motor skills and hand-eye coordination.
A newly licensed nurse has obtained a capillary glucose level from a client that produced inaccurate results and reports this to the charge nurse. Which of the following actions should the charge nurse take?
- A. Assign another nurse to be responsible for obtaining capillary glucose levels.
- B. Verify that the newly licensed nurse attended the staff education class about capillary glucose levels.
- C. Repeat the capillary glucose levels.
- D. Recheck the next scheduled capillary glucose level immediately following the nurse's.
Correct Answer: C
Rationale: The correct answer is C: Repeat the capillary glucose levels. This action should be taken to confirm the accuracy of the initial results. By repeating the test, the charge nurse can determine if the inaccuracy was due to a procedural error or if there is an issue with the equipment. This step ensures that the client receives proper care based on accurate information.
Assigning another nurse (choice A) does not address the root cause of the inaccurate results. Verifying attendance at an education class (choice B) is not as immediate or relevant as repeating the test. Rechecking the next scheduled level (choice D) without verifying the accuracy of the initial result may lead to continued inaccuracies in care.
