Nurse Jannah teaches an elderly client with right-sided weakness how to use cane. Which of the following behaviors, if demonstrated by the client to the nurse, indicates that the teaching was effective?

Correct Answer: C

Rationale: The correct answer is C because when using a cane for right-sided weakness, the client should hold the cane in the opposite hand (left hand) to provide support to the weaker side. By moving the cane forward followed by the right leg, the client maintains balance and support on the affected side, allowing for a smoother gait pattern. Moving the left leg after the right leg helps in providing stability and weight-bearing on the stronger side. Choice A is incorrect as the client should hold the cane in the opposite hand of the weakness. Choice B is incorrect as it does not provide support to the weaker side. Choice D is incorrect as it does not promote balance and stability for the client with right-sided weakness.

Correct Answer: B

Rationale: Step 1: Fowler's position elevates the head of the bed and flexes the knees, which helps expand the chest for better lung ventilation. Step 2: In a partial pneumonectomy, lung function is compromised, so optimal ventilation of the remaining lung is crucial. Step 3: By placing Tonny in Fowler's position, the diaphragm descends, allowing for better expansion of the left lung. Step 4: This position facilitates ventilation of the left lung, aiding in oxygenation and preventing complications like atelectasis. Summary: Choice B is correct as Fowler's position helps improve ventilation of the remaining lung. Choices A, C, and D are incorrect as they do not directly relate to the specific benefits of Fowler's position for post-pneumonectomy care.

Correct Answer: A

Rationale: The correct answer is A: Auscultate bowel sounds. This is the first nursing action because the client is experiencing abdominal pressure and nausea, which could indicate postoperative ileus. Auscultating bowel sounds helps assess if there is normal bowel function and potential complications. Palpating the abdomen (B) can be uncomfortable for the client post-surgery, and it may not provide immediate information on bowel function. Changing the client's position (C) may not address the underlying issue and can be done after assessing bowel sounds. Inserting a rectal tube (D) is not indicated unless there is a specific medical reason for it, which is not evident in this case.

Correct Answer: D

Rationale: Step-by-step rationale: 1. Inotropic agents directly increase the force of cardiac muscle contraction, leading to improved ventricular contractility in heart failure. 2. Beta-adrenergic blockers reduce the heart rate and contractility, opposite of the desired effect. 3. Calcium channel blockers primarily affect vascular smooth muscle and do not directly enhance cardiac contractility. 4. Diuretics help reduce fluid overload in heart failure but do not directly impact ventricular contractility. Summary: A: Beta-adrenergic blockers decrease contractility. B: Calcium channel blockers do not enhance contractility. C: Diuretics help with fluid overload but do not improve contractility. D: Inotropic agents directly increase ventricular contractility, making them the correct choice.

Correct Answer: B

Rationale: The correct answer is B: Release of tissue thromboplastin. In the extrinsic pathway of blood coagulation, tissue thromboplastin (also known as tissue factor) is released in response to tissue injury, initiating the clotting cascade. This leads to the activation of factor VII and subsequent steps in the coagulation process. A: Release of Calcium is not specific to the extrinsic pathway and does not directly initiate the clotting cascade. C: Conversion of factors XII to factor XIIa is part of the intrinsic pathway, not the extrinsic pathway. D: Conversion of factor VIII to factor VIIIa is part of the intrinsic pathway, not the extrinsic pathway.
