Correct Answer: A

Rationale: The correct answer is A. Low blood sugar levels (50 mg/dL) typically cause confusion, cold clammy skin, and an increased pulse (tachycardia). Option A correctly describes the expected symptoms of hypoglycemia, which include confusion due to the brain's inadequate glucose supply, cold and clammy skin due to sympathetic nervous system activation, and an increased pulse (110 bpm) as the body reacts to low blood sugar levels. Options B, C, and D describe symptoms that are not typically associated with hypoglycemia. Lethargy, hot dry skin, rapid deep respirations, normal vital signs, shortness of breath, distended neck veins, and bounding pulse are more indicative of other conditions or normal physiological responses, not hypoglycemia.

Correct Answer: A

Rationale: A serum albumin level of 3 g/dL is indicative of poor nutrition, which is commonly associated with pressure ulcers. This finding suggests that the client may be at risk for developing or already has a pressure ulcer due to malnutrition. High-density lipoprotein (HDL) level of 90 mg/dL (Choice B) is not directly related to pressure ulcers. The Norton scale (Choice C) is used to assess a client's risk of developing pressure ulcers, not as a finding in a client with an existing pressure ulcer. The Braden scale (Choice D) is also a tool used to assess the risk of developing pressure ulcers, not a finding in a client with an existing pressure ulcer.

Correct Answer: A

Rationale: The correct technique for administering an intramuscular (IM) injection is to locate the injection site and insert the needle at a 90-degree angle. This angle ensures that the medication is delivered into the muscle for proper absorption. Choice B is incorrect because a 45-degree angle is typically used for subcutaneous injections, not intramuscular. Choice C is incorrect as massaging the site after an injection can cause the medication to disperse unevenly. Choice D is incorrect as a 15-degree angle would not reach the muscle layer effectively for an IM injection.

Correct Answer: C

Rationale: The best strategy to ensure the safety of a client with dementia who frequently wanders is to place a bed exit alarm system. This system alerts staff when the client attempts to leave the bed, reducing the risk of falls. Choice A, using restraints, is not the best approach as it can lead to complications and is not recommended unless absolutely necessary. Choice B, encouraging the client to walk in a monitored area, may not be effective in preventing wandering as the client may still wander away. Choice D, asking family members to stay with the client at all times, may not be feasible or practical, especially for round-the-clock supervision.

Correct Answer: B

Rationale: Administering oral rehydration solutions is essential for a client with dehydration as it helps replenish lost fluids and electrolytes directly through the oral route. Monitoring electrolyte levels regularly (Choice A) is important but not as essential as providing immediate rehydration. Increasing fluid intake to maintain hydration (Choice C) may not be sufficient for a client already dehydrated and needing rapid replenishment. Administering intravenous fluids (Choice D) is a more invasive intervention typically reserved for severe cases of dehydration or when the client cannot tolerate oral fluids.
