Question 1 of 5
The client with tonsillar cancer is receiving filgrastim. Prior to administering the next dose of filgrastim, the nurse notes that the client's absolute neutrophil count is 11,000/mm3. What is the nurse's best action?
Correct Answer: C
Rationale: A: Unnecessary doses can cause leukocytosis (WBCs above 100,000/mm3), an adverse effect of filgrastim. B: A normal neutrophil count is greater than 2000/mm3. Neutropenic precautions and protective wear are unnecessary because the filgrastim has been effective in increasing the neutrophil count. C: Filgrastim (Neupogen) is a granulocyte colony-stimulating factor for treatment of neutropenia. Filgrastim is usually discontinued when the absolute neutrophil count reaches 10,000/mm3. D: A high-efficiency particulate air (HEP
A) or N95 mask rather than a regular mask should be worn if the client is severely neutropenic (less than 100/mm3).
Question 2 of 5
The client is taking methylphenidate sustained-release tablets once daily for attention deficit disorder. The medication peaks in 4 to 7 hours and has a duration of 12 hours. At which time should the nurse instruct the client to take the prescribed dose of methylphenidate?
Correct Answer: D
Rationale: Sustained-release methylphenidate (Ritalin) should be taken in the morning to avoid sleep interference.
Question 3 of 5
One day postoperative, the client complains of dyspnea, and his respiratory rate (RR) is 35, slightly labored, and there are no breath sounds in the lower-right base. The nurse should suspect:
Correct Answer: B
Rationale: No breath sounds in the lower-right base postoperative suggest atelectasis, a lung collapse common after surgery, causing dyspnea and tachypnea.
Question 4 of 5
The client with MS is prescribed baclofen. Which information is most important for the nurse to evaluate when caring for this client?
Correct Answer: B
Rationale: A: There is no serum baclofen level. B: Baclofen (Lioresal) is used primarily to treat spasticity in MS and spinal cord injuries. The nurse should assess for muscle rigidity, movement, and pain to evaluate medication effectiveness. C: Although baclofen can cause urinary urgency, this is not the most important information. D: Baclofen use is not associated with weight.
Question 5 of 5
The client has been prescribed clonidine for the unlabeled purpose of easing the discomfort associated with smoking cessation. Which body system should be the nurse's initial focus when completing the client's physical assessment?
Correct Answer: B
Rationale: Clonidine (Catapres) can cause hypotension and bradycardia, making the cardiovascular system the initial focus.
