Correct Answer: C

Rationale: The correct answer is C: Uterine body. The rationale is that the most common site of cancer for females is uterine body, specifically endometrial cancer. This is due to the high prevalence of hormonal imbalances and estrogen exposure, which are risk factors for this type of cancer. The other choices, A: Uterine cervix, B: Vagina, and D: Fallopian tube, are less common sites of cancer in females compared to the uterine body. Understanding the prevalence and risk factors associated with each site of cancer is crucial for nurses to educate clients effectively.

Correct Answer: D

Rationale: The correct answer is D: Calcium. Calcium is necessary for the chemical clotting process because it plays a crucial role in the activation of various clotting factors, leading to the formation of a blood clot. Without sufficient calcium, the clotting cascade would not be able to proceed effectively. Iron (choice A) is essential for red blood cell production, not clotting. Potassium (choice B) and Sodium (choice C) are important for various physiological functions but are not directly involved in the clotting process.

Correct Answer: B

Rationale: The correct answer is B: Take a deep breath as the nurse deflates the cuff. This is the correct choice because asking the client to take a deep breath while the cuff is deflated helps prevent aspiration of secretions into the lower airway. When the cuff is deflated, the tracheostomy tube provides a direct pathway for secretions to travel upwards, and taking a deep breath facilitates the movement of secretions out of the trachea. Choice A (Cough as the cuff is being deflated) is incorrect because coughing while the cuff is being deflated can increase the risk of aspiration as secretions may be forced into the lower airway. Choice C (Hold the breath as the cuff is being re-inflated) is incorrect as holding the breath while the cuff is being re-inflated can hinder the clearance of secretions from the trachea. Choice D (Exhale deeply as the nurse re-inflates the cuff) is incorrect

Correct Answer: B

Rationale: The correct answer is B because the client remains radioactive for a period of time after the implant removal, typically around 10 days. During this time, the nurse should take precautions to limit exposure to radiation. Choice A is incorrect because bodily fluids are not highly radioactive, and proper disposal procedures should be followed. Choice C is incorrect as soiled linens should be handled appropriately to prevent contamination. Choice D is incorrect as bed rest may not be necessary, and mobility should be encouraged within safety guidelines.

Correct Answer: B

Rationale: The correct answer is B: Encourage ambulation and liberal fluid. Encouraging ambulation can help in the movement of kidney stones and alleviate pain. Liberal fluid intake helps in flushing out kidney stones and preventing further stone formation. Incorrect options: A: Administering prescribed nephrotoxic drugs can worsen kidney function and exacerbate the pain. C: Observing aseptic principles when changing intake is important for infection prevention but not directly related to pain management for renal calculi. D: Providing a comfortable position can offer temporary relief but does not address the underlying cause of kidney stone pain.
