Correct Answer: A

Rationale: The correct action to perform before ambulating a client post total knee replacement is to assist the client to a sitting position at the edge of the bed. This step is crucial to prevent orthostatic hypotension and ensure the client is ready to stand and walk safely. Having the client march in place or raise his arms above his head are not necessary preparations for ambulation. While knowing about the client's fall history is important for safety reasons, it is not the priority action immediately before ambulating the client.

Correct Answer: A

Rationale: All patients, regardless of age, have the right to die with dignity and be free from pain. In this case, the parents' request for an opioid analgesic to relieve the child's distress aligns with the principles of palliative care and ensuring comfort. Assisted suicide involves a conscious decision by the individual, which is not applicable to a 1-month-old infant. Both the nurse and the parents have an ethical duty to ensure the infant's comfort and well-being. Withholding opioid analgesia solely to hasten death is not appropriate, as providing pain relief is a crucial aspect of end-of-life care. Opioids can be administered to dying patients at any age to alleviate suffering without the intention of hastening death. Therefore, providing analgesia during the last days and hours is an ethically appropriate nursing action. Choices B, C, and D are incorrect because the decision to administer analgesia in this scenario is based on the best interest and comfort of the infant, not concerns about assisted suicide or hastening death. The ethical consideration is to provide compassionate care and alleviate suffering.

Correct Answer: D

Rationale: Thrombocytopenia is an abnormal decrease in the number of platelets, which results in bleeding tendencies. During chemotherapy, bone marrow depression can lead to a reduction in platelet production, causing thrombocytopenia. Erythrocytosis is an abnormal increase in red blood cells, leukocytosis is an increase in white blood cells, and polycythemia is an excess of red blood cells, which is synonymous with erythrocytosis. In the context of chemotherapy, the focus is on the decrease in red and white blood cells, making thrombocytopenia the most relevant finding.

Correct Answer: A

Rationale: Transfusing neutrophils (granulocytes) to prevent infection is inappropriate in the care of a severely neutropenic client. Neutrophils normally comprise 70% of all white blood cells and can be beneficial in a selected population of infected, severely granulocytopenic clients (less than 500/mm3) who do not respond to antibiotic therapy and who are expected to experience prolonged suppression of granulocyte production. Therefore, transfusing neutrophils is not a standard practice in caring for neutropenic clients. The other choices are appropriate in caring for a severely neutropenic client: excluding raw vegetables from the diet to reduce the risk of infections from potential pathogens, avoiding administering rectal suppositories to prevent any injury or infection due to mucosal damage, and prohibiting vases of fresh flowers and plants in the client's room to minimize the risk of exposure to environmental pathogens.

Correct Answer: C

Rationale: The priority intervention for preventing respiratory complications in a client with advanced COPD who underwent gallbladder surgery is to get the client out of bed 4 times daily. This helps prevent pooling of secretions in the lungs and promotes better lung expansion. Incentive spirometry, coughing, and deep breathing are essential interventions; however, they should be performed more frequently, ideally every 1 to 2 hours, rather than every 4 hours or 4 times daily. Giving oxygen at 4 L/minute could potentially decrease the client's respiratory drive, which is not the priority in this case.
