Correct Answer: A

Rationale: The correct answer is A. Type 1 diabetes is characterized by the absence of insulin production, while Type 2 diabetes involves insulin resistance. Choice B is incorrect because Type 1 diabetes is not related to insulin resistance. Choice C is inaccurate as Type 1 diabetes is autoimmune while Type 2 diabetes is more associated with lifestyle factors. Choice D is not correct since insulin therapy is primarily used in Type 1 diabetes, whereas diet modification is a common approach in managing Type 2 diabetes.

Correct Answer: B

Rationale: The correct first action for a client with an NG tube experiencing nausea and decreased gastric secretions is to irrigate the NG tube with sterile water. This can help clear any blockages in the tube, which may be causing the symptoms. Positioning the client on their left side may be helpful for enteral feedings but is not the priority in this situation. Replacing the NG tube should not be the initial step unless irrigation fails to resolve the issue. Increasing the suction setting without attempting to clear the blockage can be harmful to the client.

Correct Answer: B

Rationale: The priority nursing action for a client with dehydration is to monitor electrolyte levels. Dehydration can cause imbalances in electrolytes such as sodium and potassium, affecting essential bodily functions. Monitoring electrolyte levels is crucial to promptly identify and correct any imbalances. While administering oral fluids (Choice A) is vital in treating dehydration, monitoring electrolyte levels takes precedence as it directly addresses the underlying imbalance. Administering antiemetics (Choice C) may be necessary for nausea and vomiting but is not the priority over electrolyte monitoring. Encouraging bed rest (Choice D) can conserve energy but is not as critical as monitoring electrolyte levels to prevent complications related to electrolyte imbalances.

Correct Answer: B

Rationale: Restlessness and agitation in clients with dementia should be addressed immediately as they can indicate underlying causes such as pain, discomfort, or unmet needs. Addressing these symptoms promptly can help prevent the escalation of behavioral issues and improve the client's quality of life. While frequent episodes of wandering at night, mild confusion during the day, and incontinence are also important issues to address in clients with dementia, restlessness and agitation usually require immediate attention to ensure the safety and well-being of the client.

Correct Answer: C

Rationale: The correct instruction for administering enoxaparin is to pinch the skin before injecting. Pinching the skin helps create a proper fold for subcutaneous injections like enoxaparin, ensuring proper delivery of the medication into the subcutaneous tissue. Choice A is incorrect because enoxaparin should be administered subcutaneously, not into the muscle. Injecting it into the muscle can lead to complications. Choice B is incorrect because massaging the injection site after administration can increase the risk of bleeding or bruising due to the anticoagulant properties of enoxaparin. Choice D is incorrect as it is a general instruction and does not specifically relate to the administration of enoxaparin.
