An elderly patient, Mr. Cruz is being cared for by nurse Bennie because of pulmonary embolism. Nurse Bennie would anticipate an order for immediate administration of:

Correct Answer: B

Rationale: The correct answer is B: heparin. Heparin is an anticoagulant used for immediate treatment of pulmonary embolism to prevent further clot formation. It acts quickly by inhibiting clotting factors. Warfarin (A) is used for long-term anticoagulation but has a slower onset. Dexamethasone (C) is a corticosteroid used for inflammation, not thrombosis. Protamine sulfate (D) is used to reverse the effects of heparin but is not indicated for initial treatment.

Correct Answer: A

Rationale: The correct answer is A: Diagnosis. After reviewing the patient's database and identifying concerning findings such as abnormal kidney function, lack of voiding, and decreased oral intake, the nurse needs to move to the diagnosis step of the nursing process. This involves analyzing the data collected to identify the patient's health problems and risks. In this case, the nurse needs to determine potential underlying issues related to the kidney function abnormalities and lack of voiding, and formulate a nursing diagnosis based on the findings. Summary of other choices: B: Planning comes after diagnosis and involves setting goals and creating a plan of care. C: Implementation follows planning and involves carrying out the plan of care. D: Evaluation is the final step of the nursing process where the nurse assesses the effectiveness of the interventions implemented.

Correct Answer: C

Rationale: The correct answer is C because flushing the central venous catheter with a heparinized solution before blood withdrawal is essential to maintain catheter patency and prevent clot formation. This step ensures the catheter is clear of any blockages, allowing for accurate blood sampling. Choice A is incorrect because assembling supplies should come after preparing the catheter. Choice B is incorrect as discarding blood before flushing the catheter may lead to inaccurate test results. Choice D is incorrect as replacing the catheter cap without flushing may lead to clot formation and catheter malfunction.

Correct Answer: C

Rationale: The correct answer is C: Myotic. Myotic eyedrops constrict the pupil, allowing aqueous humor to flow around the lens. Myotic agents, such as pilocarpine, work by stimulating the sphincter muscle of the iris. Osmotic eyedrops (A) reduce intraocular pressure, mydriatic eyedrops (B) dilate the pupil, and cycloplegic eyedrops (D) paralyze the ciliary muscle to prevent accommodation.

Correct Answer: A

Rationale: The correct answer is A: Risk for impaired skin integrity. This is the highest priority as patients with spinal cord injuries are at high risk for pressure ulcers due to immobility. Preventing skin breakdown is crucial to avoid complications. Choices B, C, and D are not as urgent. Choice B may be a concern but preventing skin breakdown takes precedence. Choices C and D are important but not life-threatening like potential skin issues in this patient population.

Correct Answer: A

Rationale: The correct answer is A: Diagnosis. The nurse should proceed to the diagnosis step of the nursing process after reviewing the patient's data. In this step, the nurse will analyze the information gathered to identify the patient's health problems and needs. Given the patient's lack of voiding, abnormal kidney function, and decreased oral intake, the nurse needs to determine the underlying issues contributing to these findings. This analysis will guide the nurse in developing a plan of care to address the patient's specific health concerns. Choice B: Planning would be premature without a clear understanding of the patient's health problems, needs, and contributing factors. Choice C: Implementation would involve carrying out interventions without a thorough understanding of the patient's health issues. Choice D: Evaluation comes after the implementation of interventions to assess their effectiveness, which cannot be done without a clear diagnosis.

Correct Answer: D

Rationale: The correct answer is D because drawing up clear insulin first when mixing two types of insulin in one syringe prevents contamination. Clear insulin is drawn up first to avoid clouding from the cloudy insulin. This ensures accurate dosing and prevents potential medication errors. A: Incorrect. Administering insulin after the first meal may lead to hypoglycemia if the client skips or delays meals. B: Incorrect. Insulin should not be injected into the deltoid muscle as it can lead to inconsistent absorption rates. C: Incorrect. Vigorously shaking the insulin vial can cause bubbles, affecting the accuracy of the dose and potentially altering its effectiveness.

Correct Answer: A

Rationale: Rationale: 1. A: Blood pressure apparatus is essential to monitor for any signs of bleeding or clot formation after carotid angioplasty. 2. B: IV infusion stand is important but not the priority for immediate postoperative monitoring. 3. C: Call bell is important for the client to call for assistance but not the priority for immediate postoperative care. 4. D: Endotracheal intubation is not necessary after a carotid angioplasty and is not a priority item for bedside care. Summary: Monitoring blood pressure is crucial for detecting complications post carotid angioplasty. IV stand, call bell, and endotracheal intubation are important but not the priority in this scenario.

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.
