An adult client has undergone a lumbar puncture to obtain cerebrospinal fluid (CSF) for analysis. After reviewing the results of the analysis, the nurse recognizes that the CSF is normal when which element is negative?
- A. Protein
- B. Glucose
- C. Red blood cells
- D. White blood cells
Correct Answer: C
Rationale: The adult with a normal CSF has no red blood cells in the CSF. Protein (15-45 mg/dL [0.15-0.45 g/L]) and glucose (50-75 mg/dL [2.8-4.2 mmol/L]) are normally present in CSF. The client may have small levels of white blood cells (0-5 cells/mcL [0-5 × 10^6/L]).

The nurse is performing range-of-motion (ROM) exercises on a client when the client unexpectedly develops spastic muscle contractions. Which interventions should the nurse implement? Select all that apply.
- A. Stop movement of the affected part.
- B. Massage the affected part vigorously.
- C. Notify the primary health care provider immediately.
- D. Force movement of the joint supporting the muscle.
- E. Ask the client to stand and walk rapidly around the room.
- F. Place continuous gentle pressure on the muscle group until it relaxes.
Correct Answer: A,F
Rationale: ROM exercises should put each joint through as full a range of motion as possible without causing discomfort. An unexpected outcome is the development of spastic muscle contraction during ROM exercises. If this occurs, the nurse should stop movement of the affected part and place continuous gentle pressure on the muscle group until it relaxes. Once the contraction subsides, the exercises are resumed using slower, steady movement. Massaging the affected part vigorously may worsen the contraction. There is no need to notify the primary health care provider unless intervention is ineffective. The nurse should never force movement of a joint. Asking the client to stand and walk rapidly around the room is an inappropriate measure.
The nurse is caring for a client who develops compartment syndrome as a result of a severely fractured arm. When the client asks why this happens, how should the nurse respond?
- A. A bone fragment has injured the nerve supply in the area.
- B. An injured artery causes impaired arterial perfusion through the compartment.
- C. Bleeding and swelling cause increased pressure in an area that cannot expand.
- D. The fascia expands with injury, causing pressure on underlying nerves and muscles.
Correct Answer: C
Rationale: Compartment syndrome is caused by bleeding and swelling within a compartment, which is lined by fascia that does not expand. The bleeding and swelling place pressure on the nerves, muscles, and blood vessels in the compartment, triggering the symptoms. Therefore, options 1, 2, and 4 are incorrect statements.
The nurse suspects that an air embolism has occurred when the client's central venous catheter disconnects from the intravenous (IV) tubing. The nurse immediately places the client on her or his left side in which position?
- A. High Fowler's
- B. Trendelenburg's
- C. Lateral recumbent
- D. Reverse Trendelenburg's
Correct Answer: B
Rationale: If the client develops an air embolism, the immediate action is to place the client in Trendelenburg's position on the left side. This position raises the client's feet higher than the head and traps any air in the right atrium. If necessary, the air can then be directly removed by intracardiac aspiration.
The nurse is caring for a newly delivered breast-feeding infant. Which intervention performed by the nurse would best prevent jaundice in this infant?
- A. Placing the infant under phototherapy
- B. Keeping the infant NPO until the second period of reactivity
- C. Encouraging the mother to breast-feed the infant every 2 to 3 hours
- D. Encouraging the mother to supplement breast-feeding with formula
Correct Answer: C
Rationale: To help prevent jaundice, the mother should feed the infant frequently in the immediate birth period because colostrum is a natural laxative and helps promote the passage of meconium. Breast-feeding should begin as soon as possible after birth while the infant is in the first period of reactivity.
The nurse suspecting that a client is developing cardiogenic shock should assess for which peripheral vascular manifestation of this complication? Select all that apply.
- A. Warm, moist skin
- B. Flushed, dry skin
- C. Cool, clammy skin
- D. Irregular pedal pulses
- E. Bounding pedal pulses
- F. Weak or thready pedal pulses
Correct Answer: C,F
Rationale: Some of the manifestations of cardiogenic shock include increased pulse (weak and thready); decreased blood pressure; decreasing urinary output; signs of cerebral ischemia (confusion, agitation); and cool, clammy skin. None of the remaining options are associated with the peripheral vascular aspects of cardiogenic shock.
