Correct Answer: C

Rationale: Black, tarry stools can indicate gastrointestinal bleeding, which is a serious complication of peptic ulcer disease. This finding suggests active bleeding in the gastrointestinal tract, requiring immediate attention. A normal heart rate of 72 beats per minute (choice A) is within the expected range. A hemoglobin level of 12 g/dL (choice B) is also within normal limits. Nausea and vomiting (choice D) are common symptoms associated with peptic ulcer disease but may not necessarily indicate active bleeding like black, tarry stools.

Correct Answer: D

Rationale: The correct answer is to check the client's oxygen saturation level first. This action is crucial in assessing the severity of dyspnea and determining the necessity for oxygen therapy. Administering oxygen therapy without knowing the current oxygen saturation level can be inappropriate and potentially harmful. Encouraging deep breathing exercises and raising the head of the bed are important interventions, but assessing the oxygen saturation level takes precedence in managing dyspnea in a client with COPD.

Correct Answer: C

Rationale: When a client is receiving intravenous antibiotics, checking the IV site for signs of phlebitis is a priority assessment for the nurse. Phlebitis is an inflammation of the vein, which can lead to serious complications such as infection and thrombosis. Monitoring the IV site helps prevent these complications and ensures the safe delivery of antibiotics. While monitoring the client's temperature, pain level, and respiratory status are important assessments, they are not the priority in this scenario where IV antibiotic administration requires close monitoring for complications like phlebitis.

Correct Answer: B

Rationale: The correct answer is B. When discussing infant feeding skills, it is important to note that eating foods higher in fat is not considered a specific feeding skill for newborns. The typical progression of feeding skills includes pushing solid objects from the mouth, eating pieces of soft, cooked food, drinking from a cup held by another person, and experimenting with a spoon. Choices A, C, and D correspond to the expected developmental sequence of feeding skills for infants, making them incorrect answers in this context.

Correct Answer: C

Rationale: When caring for a client with a new tracheostomy, the priority assessment is checking the tracheostomy site for signs of infection. This is essential to detect early signs of complications such as infection, which can lead to serious issues. Monitoring oxygen saturation is important but not as critical as ensuring the tracheostomy site is free from infection. Pain assessment and level of consciousness are also important but secondary to assessing for signs of infection in this scenario.
