Correct Answer: A

Rationale: The best intervention to prevent falls in a client with dementia who gets out of bed unsupervised is to place a bed exit alarm. This device alerts staff when the client attempts to leave the bed, allowing timely intervention to reduce the risk of falls. Using restraints (choice B) can lead to physical and psychological harm and should be avoided unless absolutely necessary. Asking the client's family to stay at the bedside (choice C) may not be feasible at all times and does not provide a continuous monitoring solution. Encouraging frequent ambulation with assistance (choice D) is beneficial for mobility but may not address the immediate risk of falls associated with unsupervised bed exits.

Correct Answer: A

Rationale: The correct answer is A: 'Sweating and trembling.' These are classic early signs of hypoglycemia in a diabetic patient. Sweating occurs due to the activation of the sympathetic nervous system in response to low blood sugar levels, while trembling is a result of the body's attempt to increase muscle activity to raise blood sugar levels. Confusion and irritability (Choice B) are more advanced signs of hypoglycemia that occur if the condition is not treated promptly. Dizziness and increased heart rate (Choice C) can also occur but are not as specific and early as sweating and trembling. Nausea and vomiting (Choice D) are more commonly associated with other conditions or severe hypoglycemia, rather than being early signs.

Correct Answer: A

Rationale: The most appropriate intervention for a client with dementia at risk of falls is to use a bed exit alarm to notify staff of attempts to leave the bed. This intervention allows for timely assistance and prevents falls. Raising all four side rails (Choice B) can lead to entrapment or agitate the client. Encouraging frequent ambulation with assistance (Choice C) may not be suitable for a client at high risk of falls. Using restraints (Choice D) should be avoided as they can increase agitation, risk of injury, and have ethical implications.

Correct Answer: B

Rationale: Late decelerations indicate uteroplacental insufficiency, and the priority nursing action is to improve placental perfusion. Positioning the client on their side, particularly the left side, can enhance blood flow to the placenta and fetus by reducing pressure on the vena cava and increasing cardiac output. Applying oxygen, although helpful, is not the initial priority in this situation. Calling for a Cesarean delivery is not warranted unless other interventions fail to correct the late decelerations. Administering oxytocin can worsen the condition by increasing uterine contractions, exacerbating fetal distress.

Correct Answer: B

Rationale: The correct answer is B because prolonged use of corticosteroids is a known risk factor for infections. Choice A is incorrect because frequent hand washing actually helps prevent infections. Choice C is incorrect as patient interaction is essential in healthcare but should be done following proper infection control measures. Choice D is also incorrect as restricting client movement is not a standard practice to prevent contamination.
