Correct Answer: D

Rationale: Instructing the client to sit upright while eating is crucial to prevent aspiration in stroke clients. This position helps in safe swallowing and reduces the risk of food or liquid entering the airway. Encouraging the client to take large bites of food (Choice A) can increase the risk of choking and aspiration. Advising the client to eat quickly (Choice B) may lead to fatigue and compromise safe swallowing. Offering thin liquids (Choice C) can also increase the risk of aspiration in stroke clients, as thicker liquids are usually recommended to prevent aspiration.

Correct Answer: B

Rationale: The correct answer is the upper outer thigh. In thin, elderly clients, the upper outer thigh is a recommended site for subcutaneous injections due to the presence of adequate subcutaneous tissue and muscle mass. The dorsal aspect of the upper arm may not provide enough subcutaneous tissue for proper absorption of the medication. The lower abdomen is not ideal for thin individuals as it may lead to injection into muscle rather than subcutaneous tissue. The lateral aspect of the upper arm is also not a commonly recommended site for subcutaneous injections.

Correct Answer: D

Rationale: The correct answer is D: Notify the healthcare provider immediately. A drop in platelet count during heparin therapy may indicate heparin-induced thrombocytopenia (HIT), a serious condition that increases the risk of clot formation. Immediate discontinuation of heparin is necessary to prevent further complications. Administering platelet transfusion without addressing the underlying cause can be harmful. Continuing to monitor the platelet count without taking immediate action can lead to delayed intervention. Notifying the healthcare provider promptly allows for assessment and initiation of alternative anticoagulation therapy to manage the client's condition effectively.

Correct Answer: B

Rationale: The correct answer is B. Pale mucous membranes, such as those of the eyelids and lips, are a classic sign of anemia in infants. Anemia leads to decreased oxygen-carrying capacity, resulting in tissue hypoxia, which can manifest as pale mucosa. Choice A, a hemoglobin level of 12 g/dL, is within the normal range for a 10-month-old infant and would not necessarily indicate anemia. Choice C, hypoactivity, is a non-specific finding and can be present in various conditions, not specifically anemia. Choice D, a heart rate between 140 to 160, is within the normal range for an infant and is not a specific finding associated with anemia.

Correct Answer: C

Rationale: Irrigating and redressing a leg wound is a common task within the PN's scope of practice, making this assignment appropriate. Tasks like testing stool specimens for occult blood and assisting with ambulation of a client with a chest tube may require a higher level of training and assessment, typically performed by RNs. Admitting a client from the emergency room involves a comprehensive assessment and decision-making process, which is usually within the RN's responsibility.
