A nurse is caring for a client who is receiving chemotherapy. The client's most recent lab results show a white blood cell count of 3,100/mm3, and a platelet count of 280,000/mm3. Based on these lab results, which nursing action is appropriate for this client?

Provide the client with an electric shaver for grooming.

Move the client to a negative pressure isolation room.

Encourage the client to select cooked vegetables rather than a salad for their lunch tray.

Educate the client to dab their nose, rather than forcefully blow their nose.

Answer and Explanation

The Correct Answer is A

A.   This option is appropriate because the client's low white blood cell count (3,100/mm³) suggests they are at risk for infection due to chemotherapy-induced immunosuppression. Using an electric shaver reduces the risk of cuts and nicks that could potentially lead to infections.

B.   This option is not necessary based on the client's current lab results. Negative pressure isolation rooms are typically reserved for clients with severely compromised immune systems, such as those with very low neutrophil counts (neutropenia). A white blood cell count of 3,100/mm³ is within a range where standard precautions are usually sufficient.
C.   This option addresses food safety precautions for clients with neutropenia (low white blood cell count). Raw vegetables, including salads, have a higher risk of harboring bacteria that could cause infections. Therefore, cooked vegetables are safer for clients with compromised immune systems.
D.   This option is appropriate because chemotherapy-induced thrombocytopenia (low platelet count of 280,000/mm³) increases the risk of bleeding. Forceful blowing of the nose can traumatize the nasal mucosa and increase the risk of nosebleeds. Dabbing the nose gently is a safer method to avoid nosebleeds.

Correct Answer is D

Explanation

A. Dopamine is primarily associated with other neurodegenerative disorders such as Parkinson's disease, not Alzheimer's disease. In Alzheimer's disease, the focus is on changes related to beta-amyloid plaques and neurofibrillary tangles rather than alterations in dopamine levels.
B. Glial cells, including astrocytes and microglia, play a role in the brain's immune response and support of neurons. In Alzheimer's disease, there is evidence of increased activation and proliferation of glial cells in response to neuroinflammation and the presence of beta-amyloid plaques and neurofibrillary tangles. This reactive gliosis is a secondary response to the underlying pathology.
C. Glutamate is an excitatory neurotransmitter involved in various brain functions, including memory and learning. In Alzheimer's disease, there is evidence of dysregulation in glutamate metabolism and

signaling pathways. This dysregulation can lead to excitotoxicity, which contributes to neuronal damage and cell death seen in the disease.
D. Neurofibrillary tangles are one of the hallmark pathological features of Alzheimer's disease. These tangles are aggregates of hyperphosphorylated tau protein that accumulate inside neurons, disrupting their normal functioning and eventually leading to cell death. Neurofibrillary tangles, along with beta- amyloid plaques, contribute to the progressive cognitive decline observed in Alzheimer's disease.

A. If you experience a headache after taking this medication, discontinue its use and seek medical attention. B. If the first tablet does not relieve your chest pain, you may take a second tablet 10 minutes later. C. Stand up slowly after taking this medication. D. Replace this medication every 3 months.

Correct Answer is B

Explanation

A. Headache is a common side effect of nitroglycerin due to its vasodilatory effects, especially in the head. Most headaches associated with nitroglycerin are mild and transient. Patients are generally advised to continue using the medication as prescribed unless the headache is severe or persistent.
B. Nitroglycerin tablets are used for the immediate relief of angina symptoms. If the first tablet does not adequately relieve chest pain within 5 minutes, the patient can take a second tablet. If the pain persists after the second tablet, emergency medical attention should be sought. However, it's important to note that the maximum number of tablets that can be taken within a short period should be specified by the healthcare provider, typically 2 or 3 tablets in 15 to 30 minutes.
C. Nitroglycerin can cause orthostatic hypotension, which is a drop in blood pressure upon standing up. This can lead to dizziness or fainting. Therefore, patients should be advised to stand up slowly after taking nitroglycerin to minimize the risk of falls or injury.
D. Nitroglycerin tablets are sensitive to light, heat, and moisture, which can reduce their effectiveness over time. Therefore, it's recommended to replace nitroglycerin tablets every 3 to 6 months to ensure potency and effectiveness.
