A nurse is planning an educational program for high school students about cigarette smoking. Which of the following potential consequences of smoking is most likely to discourage adolescents from using tobacco?

Correct Answer: C

Rationale: The most likely consequence to discourage adolescents from smoking is the immediate effect of decreased athletic ability. This consequence is more tangible and relevant to high school students compared to long-term health risks like lung cancer or addiction. While choices A, B, and D are all negative outcomes of smoking, choice C is more likely to have a direct impact on adolescents due to its immediate and visible effects on their physical performance.

Correct Answer: C

Rationale: The best intervention for a client with dementia who frequently attempts to get out of bed unsupervised is to use a bed exit alarm system (Choice C). A bed exit alarm can alert staff when the client tries to leave the bed, helping to prevent falls. Using restraints (Choice A) is not recommended as it can lead to physical and psychological harm. While having family members present (Choice B) can be beneficial, it may not be feasible at all times. Keeping the client's room dark and quiet (Choice D) may not address the immediate safety concern of the client attempting to get out of bed.

Correct Answer: A

Rationale: The correct answer is A. Positive urine glucose and acetone could indicate gestational diabetes or preeclampsia, both of which are complications. Choice B, pedal edema, is common in pregnancy but may also be a sign of preeclampsia if severe. Choice C, an increase in vaginal discharge, is a normal finding in pregnancy due to hormonal changes. Choice D, pressure against the diaphragm when the baby moves, is a normal sensation due to the growing uterus displacing abdominal contents.

Correct Answer: A

Rationale: The correct procedure for inserting a nasogastric (NG) tube involves measuring the tube to ensure the appropriate length for insertion and using lubrication to reduce discomfort and aid in smooth insertion. Choice B is incorrect as measuring the tube is essential for proper placement. Choice C is incorrect as lubrication helps in easing the insertion process. Choice D is incorrect as checking the placement comes after insertion and should not be done simultaneously with the insertion process.

Correct Answer: B

Rationale: The correct answer is B because administering insulin lispro to an NPO client can lead to hypoglycemia due to the lack of food to balance the medication. This situation poses a serious risk to the client's safety and should be documented in an incident report. Choice A is not as critical as insulin administration for an NPO client. Choice C is also serious but does not pose an immediate risk to the client's health. Choice D, administering anticoagulants without checking the INR, is important but does not require an incident report unless adverse effects occur, as it may not immediately endanger the client's life.

Correct Answer: A

Rationale: Using a bed exit alarm system is crucial in minimizing the risk of injury for a client with dementia. This intervention helps alert staff when the client is attempting to leave the bed, reducing the chances of falls. Raising all four side rails while the client is in bed (Choice B) can lead to restraint-related issues and is not recommended unless necessary for safety reasons. Applying a soft wrist restraint (Choice C) is generally not the first choice in managing clients with dementia due to the risk of complications and loss of mobility. Dimming the lights in the client's room (Choice D) may not directly address the risk of injury associated with dementia and may even increase the risk of falls due to poor visibility.

Correct Answer: D

Rationale: The correct intervention for the nurse to include in the plan of care for a client undergoing total parenteral nutrition (TPN) is to change the TPN tubing every 24 hours. Changing the tubing at regular intervals helps reduce the risk of infection associated with central venous catheters. Monitoring electrolyte levels daily (Choice A) is important but not specific to TPN. Weighing the client daily (Choice B) is important for monitoring fluid status but not directly related to TPN. Monitoring blood glucose levels every 6 hours (Choice C) is essential for clients receiving TPN, but changing the tubing is a more critical intervention to prevent infections.

Correct Answer: B

Rationale: The correct lifestyle change that should be emphasized for a client with hypertension is to limit the intake of high-fat foods. High-fat foods can contribute to high blood pressure, so reducing their consumption is important in managing hypertension. Choice A is incorrect because increasing intake of sodium-rich foods can worsen hypertension due to their effect on blood pressure. Choice C is incorrect as caffeinated beverages can also elevate blood pressure. Choice D is incorrect because while high-protein foods can be beneficial, they do not directly lower blood pressure like reducing high-fat foods would.

Correct Answer: B

Rationale: To administer 10 mg of metoclopramide, the nurse should administer 2 mL (10 mg / 5 mg per mL). Therefore, the correct answer is 2 mL. Choice A (1 mL) is incorrect because it would only deliver 5 mg of metoclopramide, which is half the required dose. Choice C (3 mL) and D (4 mL) are incorrect as they would provide more than the required dose of 10 mg.
