The healthcare provider is preparing a client with deep vein thrombosis (DVT) for a Venous Doppler evaluation. Which of the following would be necessary for preparing the client for this test?

Correct Answer: D

Rationale: No special preparation is required for a Venous Doppler evaluation. Option A is incorrect because there is no need for the client to be NPO (nothing by mouth) before this test. Option B is incorrect as sedative medication is not typically administered for a Venous Doppler evaluation. Option C is incorrect as discontinuing anticoagulant therapy before the test may not be safe for a client with DVT, as it could increase the risk of developing a blood clot. Therefore, the correct answer is D.

Correct Answer: D

Rationale: The correct answer is D. During the anger stage of grief, it is essential for the nurse to reassure the client that anger is a normal reaction to a cancer diagnosis. This validation of the client's emotions can help in providing emotional support. Choice A is incorrect because discussing risk factors for colorectal cancer does not address the client's current emotional state. Choice B is incorrect because focusing teaching on the client's future management does not directly address the client's need for emotional support in the present. Choice C is incorrect because providing written information about loss and grief phases is not as immediately comforting as directly reassuring the client about his feelings of anger.

Correct Answer: B

Rationale: The correct answer is B: Droplet. Droplet precautions are required for infections that spread via droplets larger than 5 microns in diameter, such as pharyngeal diphtheria. Contact precautions are used for diseases that spread by direct or indirect contact. Airborne precautions are for diseases that spread through small particles in the air. Protective precautions are not a standard precautionary measure for specific infections like pharyngeal diphtheria.

Correct Answer: B

Rationale: Measuring the pH of the gastric aspirate is the most reliable method to confirm proper placement of an NG tube. Gastric fluid has an acidic pH, typically ranging from 1 to 5. Assessing the client for a gag reflex (choice A) is important for airway protection but does not confirm tube placement. Placing the NG tube in water to observe for bubbling (choice C) is incorrect and not a reliable method for verifying placement. Auscultating 2.5 cm above the umbilicus while injecting sterile water (choice D) is an outdated method and is not recommended for verifying NG tube placement.

Correct Answer: A

Rationale: Weight loss is a common finding in clients with hyperthyroidism due to increased metabolic activity. Hyperthyroidism leads to an overactive thyroid gland, which results in an increased metabolic rate and often leads to weight loss despite a normal or increased appetite. Cold intolerance (Choice B) is more commonly associated with hypothyroidism, where the body's processes slow down. Bradycardia (Choice C) is a slow heart rate, which is not typically seen in hyperthyroidism; rather, tachycardia or an increased heart rate is more common. Dry skin (Choice D) is also not a typical finding in hyperthyroidism, as the skin is more likely to be warm and moist due to increased metabolic activity.

Correct Answer: A

Rationale: Performing a bladder scan is the initial step to assess for urinary retention in a postoperative client. This non-invasive technique helps determine the volume of urine in the bladder, guiding further interventions. Encouraging the client to drink fluids (Choice B) may be beneficial but is not the priority when assessing for urinary retention. Inserting a straight catheter (Choice C) should not be the initial action without first assessing for retention. Administering a diuretic (Choice D) should not be done without confirming the need through assessment.

Correct Answer: B

Rationale: The most important action to prevent infection in a client with an indwelling urinary catheter is to ensure the catheter tubing is free of kinks. This action helps prevent obstruction, ensures proper drainage, and reduces the risk of infection. Changing the catheter every 72 hours is not necessary unless clinically indicated and may introduce unnecessary risk. Cleaning the perineal area with antiseptic solution daily is important for general hygiene but not the most critical action for catheter-related infection prevention. Irrigating the catheter with normal saline every shift is not a routine nursing intervention for catheter care and may increase the risk of introducing pathogens.

Correct Answer: C

Rationale: The correct technique for using a flow-oriented incentive spirometer involves breathing in slowly and deeply to raise the ball or piston. This action helps to expand the lungs and improve lung function. Option A is incorrect as coughing deeply after each use is not part of using the spirometer. Option B is incorrect as holding the breath for 10 seconds is not the correct instruction for using the spirometer. Option D is incorrect as exhaling forcefully before using the spirometer is not the appropriate step in using this device.

Correct Answer: A

Rationale: The correct action for the nurse to take in this situation is to notify the provider about the client's decision. By informing the provider, they can discuss the client's change in decision, explore the reasons behind it, and determine the appropriate course of action. Proceeding with the transport (Choice B) without addressing the client's concerns would not respect the client's autonomy and right to make decisions about their own healthcare. Preparing the surgical site (Choice C) would be premature and inappropriate if the client no longer wishes to proceed with the surgery. While documenting the client's statement (Choice D) is important for documentation purposes, the immediate priority is to involve the provider in the decision-making process.
