Correct Answer: B

Rationale: The correct answer is B, which is low-molecular-weight heparin doses. After hip replacement surgery, patients are at risk of developing deep vein thrombosis (DVT) due to immobility. Heparin and low-molecular-weight heparin are commonly used for prophylaxis against DVT. Monitoring for hemorrhage is crucial when administering anticoagulants. Choices A, C, and D are not directly related to monitoring for hemorrhage in this scenario. Thick, tenacious pulmonary secretions (Choice A) may indicate respiratory issues, SCDs (Choice C) help prevent DVT but do not directly relate to hemorrhage monitoring, and elastic stockings (TED hose) (Choice D) are used for DVT prophylaxis but do not alert to hemorrhage.

Correct Answer: A

Rationale: The correct answer is A. Positioning the irrigating solution bag 30 inches below the stoma would cause discomfort and ineffective irrigation as the bag should be positioned at a lower level. Option B is incorrect because a closed system for irrigation is the preferred method for colostomy irrigation. Option C is incorrect as colostomy irrigation is typically done once a day unless otherwise instructed by a healthcare provider. Option D is incorrect as the stoma should be cleaned with mild soap and water to prevent skin irritation and damage.

Correct Answer: B

Rationale: Teaching about a healthy diet is considered a primary prevention activity. Primary prevention aims to prevent the onset of a disease or health problem. Educating individuals on healthy lifestyle choices, such as diet modification, falls under primary prevention. Providing cholesterol screening (choice A) is a secondary prevention measure aimed at early detection. Offering information about antihypertensive medications (choice C) falls under secondary prevention, focusing on controlling risk factors. Developing a list of cardiac rehabilitation programs (choice D) is part of tertiary prevention, focusing on rehabilitation and improving outcomes post-disease onset.

Correct Answer: A

Rationale: The correct action for the nurse to take in this situation is to ask the client why she has changed her mind. By understanding the client's reasons for refusal, the nurse can address any concerns, provide further information, and ensure that the client's decision is respected. Proceeding with the surgery without clarifying the client's decision or notifying the surgeon immediately would not be appropriate. Documenting the client's decision is important, but it should be done after understanding the rationale behind the decision.

Correct Answer: B

Rationale: Restlessness and increased mucus production are common signs of gastrointestinal issues or reflux in infants, which could explain the symptoms of spitting up and excessive gas. Increased temperature and lethargy (Choice A) are more indicative of an infection rather than gastrointestinal issues. Increased sleeping and listlessness (Choice C) are not typical signs associated with the symptoms described. Diarrhea and poor skin turgor (Choice D) are not directly related to the symptoms of spitting up and gas in this scenario.
