A nurse is reviewing hematology laboratory results of a client receiving intravenous chemotherapy for leukemia. Which of the following laboratory findings prompts the nurse to initiate neutropenic precautions?

A white blood cell count of 1000/mm3

A red blood cell count of 5 million/mm3

A clotting time of 10 minutes

A thrombocyte count of 90,000 cells/mm3

Answer and Explanation

The Correct Answer is A

Choice A reason: This is correct. A white blood cell count of 1000/mm3 indicates severe neutropenia, which is a condition of having abnormally low levels of neutrophils, a type of white blood cell that fights infections. Neutropenic precautions are measures to protect the client from exposure to pathogens, such as wearing a mask, gloves, and gown, avoiding contact with sick people, and practicing good hygiene.

Choice B reason: This is incorrect. A red blood cell count of 5 million/mm3 is within the normal range for both males and females. It does not indicate any risk of infection or bleeding.

Choice C reason: This is incorrect. A clotting time of 10 minutes is also within the normal range, which is 8 to 15 minutes. It does not indicate any risk of infection or bleeding.

Choice D reason: This is incorrect. A thrombocyte count of 90,000 cells/mm3 is low, but not low enough to require neutropenic precautions. Thrombocytes, also known as platelets, are responsible for blood clotting. A low thrombocyte count increases the risk of bleeding, but not infection. The normal range for thrombocyte count is 150,000 to 450,000 cells/mm3.

Correct Answer is A

Explanation

Choice A reason:Swaying during a Romberg test indicates a positive result, suggesting proprioceptive deficits or sensory ataxia.

Choice B reason: Unequal pupil response to light relates to cranial nerve function, not balance assessed by the Romberg test.

Choice C reason: This is incorrect. Patient taking two attempts to touch their nose while their eyes are closed is a mild impairment of coordination, which may be due to neurologic changes or other factors such as fatigue or medication. This is not a significant finding that requires immediate attention.

Choice D reason: This is incorrect. Patient complaining of mild dizziness is a common symptom of neurologic changes or vestibular dysfunction. It is not a serious finding that requires immediate attention. The nurse should monitor the patient and provide comfort measures.

A. arm and leg weakness, paresthesia, blurred vision, and facial frown. B. uncontrollable rapid jerky movements in arms, trunk and facial muscles. C. stumbling, backward tilt of the head, quick fluttering hand movements, and quick uncontrolled gait. D. hand tremors, bradykinesia, skeletal muscle rigidity, and postural instability.

Correct Answer is D

Explanation

Choice A reason: This is incorrect. Arm and leg weakness, paresthesia, blurred vision, and facial frown are not specific to Parkinson disease, but may be seen in other neurological disorders, such as multiple sclerosis or stroke.

Choice B reason: This is incorrect. Uncontrollable rapid jerky movements in arms, trunk and facial muscles are characteristic of Huntington disease, not Parkinson disease. Huntington disease is a genetic disorder that causes progressive degeneration of the nerve cells in the brain.

Choice C reason: This is incorrect. Stumbling, backward tilt of the head, quick fluttering hand movements, and quick uncontrolled gait are signs of cerebellar ataxia, not Parkinson disease. Cerebellar ataxia is a disorder that affects the coordination and balance of the movements, caused by damage to the cerebellum.

Choice D reason: This is correct. Hand tremors, bradykinesia, skeletal muscle rigidity, and postural instability are the cardinal signs and symptoms of Parkinson disease. Parkinson disease is a chronic and progressive disorder that affects the dopamine-producing neurons in the brain, resulting in movement problems.
