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: D

Rationale: The correct answer is 'D: All of the above.' Edema, hypertension, and shortness of breath are key signs of fluid overload, particularly common in patients with heart failure. Edema refers to the swelling caused by excess fluid trapped in the body's tissues, hypertension can be a result of fluid volume overload, and shortness of breath can occur due to fluid accumulation in the lungs. Therefore, all these signs collectively indicate fluid overload in a patient. Choices A, B, and C are incorrect individually as each alone may not necessarily indicate fluid overload, but when seen together, they strongly suggest fluid volume excess in the body.

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: B

Rationale: The correct answer is B. Using a bed exit alarm system is a non-restrictive intervention that alerts staff when the client tries to leave the bed, promoting safety and preventing falls. Choice A is incorrect because using restraints can have adverse effects and should be avoided whenever possible. Choice C is not the priority for a client at risk of falls due to dementia as it may increase the risk of falls without proper supervision. Choice D is also not recommended as raising all four side rails can lead to restraint and should be used cautiously, if at all. Therefore, the best option is to use a bed exit alarm system to ensure the client's safety while allowing some freedom of movement.

Correct Answer: A

Rationale: The correct action for early decelerations, which are caused by fetal head compression and are considered normal during labor, is to continue monitoring the fetal heart rate. Early decelerations mirror contractions and usually do not require any intervention. Stopping the oxytocin infusion (Choice B) is not necessary as early decelerations are not typically a cause for concern related to oxytocin. Performing a vaginal examination (Choice C) or initiating an amnioinfusion (Choice D) are unnecessary and not indicated specifically for early decelerations.
