A client with acquired immunodeficiency syndrome (AIDS) has Pneumocystis carinii (PCP). What is the nurse's priority assessment for this client?

Choice A reason: Fowler's position is a semisitting position with the head of the bed elevated at 45 to 60 degrees. This position allows for maximum expansion of the chest and improves ventilation and oxygenation. It also reduces the work of breathing and prevents the abdominal organs from compressing the diaphragm.

Choice B reason: Sim's position is a sidelying position with the lower arm behind the back and the upper knee flexed. This position is used for patients who are unconscious, have difficulty swallowing, or are receiving an enema. It does not facilitate breathing or oxygenation for patients with COPD.

Choice C reason: Prone position is a lying position with the face down and the arms at the sides or bent at the elbows. This position is used for patients with acute respiratory distress syndrome (ARDS) or severe lung injury to improve oxygenation and reduce lung inflammation. It is not recommended for patients with COPD as it may increase the risk of aspiration, pressure ulcers, and nerve damage.

Choice D reason: Lateral position is a sidelying position with the upper leg slightly flexed and supported by a pillow. This position is used for patients who are resting or sleeping to prevent pressure ulcers and promote comfort. It does not improve breathing or oxygenation for patients with COPD.

Choice A reason: Deeply palpating the area for rebound tenderness is not the nurse's next action, because it is inappropriate and dangerous. Deeply palpating the area for rebound tenderness is a test that involves applying and releasing pressure on the abdomen, which can elicit pain or discomfort in the presence of peritonitis or appendicitis. Deeply palpating the area for rebound tenderness is not relevant or useful for the client's complaint of pain and burning in the right calf area, which may indicate a deep vein thrombosis (DVT), which is a blood clot in the deep veins of the leg. Deeply palpating the area for rebound tenderness can also worsen the pain, damage the tissues, or dislodge the clot, which can cause pulmonary embolism, which is a lifethreatening condition.

Choice B reason: Percussing over the area for a change in tone is not the nurse's next action, because it is inappropriate and useless. Percussing over the area for a change in tone is a test that involves tapping on the chest or abdomen, which can produce different sounds depending on the density of the underlying organs or tissues. Percussing over the area for a change in tone is not relevant or useful for the client's complaint of pain and burning in the right calf area, which may indicate a deep vein thrombosis (DVT), which is a blood clot in the deep veins of the leg. Percussing over the area for a change in tone can also worsen the pain, damage the tissues, or dislodge the clot, which can cause pulmonary embolism, which is a lifethreatening condition.

Choice C reason: Comparing the circumference to the left calf is the nurse's next action, because it is appropriate and useful. Comparing the circumference to the left calf is a test that involves measuring the size of the leg, which can reveal any swelling or edema in the affected area. Comparing the circumference to the left calf is relevant and useful for the client's complaint of pain and burning in the right calf area, which may indicate a deep vein thrombosis (DVT), which is a blood clot in the deep veins of the leg. Comparing the circumference to the left calf can also help diagnose, monitor, or treat the condition, as a difference of more than 2 cm between the legs can suggest a DVT.

Choice D reason: Medicating the client for pain and reassessing in 60 minutes is not the nurse's next action, because it is inappropriate and delayed. Medicating the client for pain and reassessing in 60 minutes is an intervention that involves giving the client a painkiller and checking the response after an hour. Medicating the client for pain and reassessing in 60 minutes is not relevant or useful for the client's complaint of pain and burning in the right calf area, which may indicate a deep vein thrombosis (DVT), which is a blood clot in the deep veins of the leg. Medicating the client for pain and reassessing in 60 minutes can also mask the symptoms, delay the diagnosis, or miss the opportunity to prevent the complications, such as pulmonary embolism, which is a lifethreatening condition.
