A nurse is assessing a patient who has a history of deep vein thrombosis (DVT). Which of the following findings would be most concerning?

Correct Answer: C

Rationale: The correct answer is C: Shortness of breath and chest pain. This is most concerning because it could indicate a pulmonary embolism, a serious complication of DVT where a blood clot travels to the lungs. Shortness of breath and chest pain are signs of compromised respiratory and cardiac function. A: Pain and swelling in the leg are common symptoms of DVT but not as concerning as symptoms of a pulmonary embolism. B: Redness and warmth around the affected area are typical signs of inflammation associated with DVT but do not indicate a life-threatening complication like a pulmonary embolism. D: Pale skin and decreased pulse in the affected leg could be signs of compromised circulation due to DVT, but they are not as immediately life-threatening as symptoms of a pulmonary embolism.

Correct Answer: A

Rationale: The correct answer is A: Administer epinephrine. This is the first step in the care of a client with a severe allergic reaction because epinephrine is the primary medication used to reverse the life-threatening symptoms of anaphylaxis. Epinephrine acts quickly to constrict blood vessels, relax smooth muscles in the lungs to improve breathing, and increase heart rate. Administering epinephrine promptly can prevent progression to severe outcomes like respiratory failure or shock. Corticosteroids (B and C) are used as adjunct therapy and do not provide immediate relief. Applying a cold compress (D) does not address the systemic effects of anaphylaxis and can delay potentially life-saving treatment.

Correct Answer: A

Rationale: The correct answer is A: Administer antibiotics. Antibiotics are crucial in treating wound infections as they target and eliminate the infection-causing bacteria, preventing the infection from spreading and promoting healing. Applying a cold compress (choice B) or heat (choice C) may provide temporary relief but do not address the underlying infection. Administering IV fluids (choice D) may be necessary for hydration, but it does not directly treat the infection. Antibiotics directly target the infection, making it the most important intervention for a client with a wound infection.

Correct Answer: A

Rationale: The correct answer is A: Check for signs of infection. This is crucial because chemotherapy weakens the immune system, increasing the risk of infections. Signs of infection such as fever, chills, sore throat, and cough should be closely monitored to prevent serious complications. Monitoring weight (B) and nutrition (C) are important but not as critical as detecting infections promptly. Checking for skin changes (D) is also important, but it is secondary to identifying and managing infections due to the immediate threat they pose to the client's health.

Correct Answer: C

Rationale: The correct quadrant for tenderness in suspected appendicitis is the lower right quadrant (Choice C). This is because the appendix is located in the lower right abdomen. Appendicitis typically presents with pain starting around the navel and then localizing to the lower right quadrant. The other choices, upper right (Choice A), upper left (Choice B), and lower left (Choice D) are incorrect as they do not correspond to the typical location of the appendix. Upper right quadrant is where the liver and gallbladder are situated, upper left quadrant contains the stomach and spleen, and lower left quadrant has the colon and left ovary/testis.
