A nurse is admitting a client who has diabetic ketoacidosis. Which of the following types of continuous infusions should the nurse initiate?
0.45% saline
NPH insulin
0.9% normal saline
Glargine insulin
The Correct Answer is C
A. 0.45% saline. This is a hypotonic solution, which may be used later in diabetic ketoacidosis (DKA) management, but it is not appropriate for initial fluid resuscitation as it does not rapidly expand intravascular volume.
B. NPH insulin. NPH is an intermediate-acting insulin and is not used for continuous infusion. In DKA, rapid insulin correction is needed, typically with a short-acting insulin like regular insulin.
C. 0.9% normal saline. This isotonic fluid is the first-line choice for fluid replacement in clients with DKA. It helps restore circulating volume and correct dehydration quickly, which is a critical initial intervention.
D. Glargine insulin. Glargine is a long-acting insulin and not suitable for IV infusion. DKA requires the use of short-acting insulin (e.g., regular insulin) administered via IV infusion to correct hyperglycemia and acidosis.

Correct Answer is D
Explanation
A. Naltrexone. This medication is used for opioid and alcohol use disorders. It helps reduce cravings and the pleasurable effects of those substances but is not indicated for smoking cessation.
B. Chlordiazepoxide. This is a benzodiazepine used to manage alcohol withdrawal symptoms, such as anxiety, tremors, and agitation. It is not appropriate for treating nicotine dependence.
C. Clonidine. Although primarily used for hypertension, clonidine has been used off-label to manage symptoms of opioid or nicotine withdrawal. However, it is not the first-line agent for smoking cessation.
D. Bupropion. This is an antidepressant also approved for smoking cessation. It helps reduce nicotine cravings and withdrawal symptoms and is often prescribed under the brand name Zyban for this purpose.
Correct Answer is D
Explanation
A. Offer the client saltine crackers between meals. Saltine crackers are dry and salty, which can worsen symptoms of xerostomia (dry mouth) by further irritating and drying the oral mucosa. Moist, soft foods are more appropriate.
B. Suggest rinsing his mouth with an alcohol-based mouth wash. Alcohol-based mouthwashes should be avoided in clients with dry mouth as they can exacerbate oral dryness and irritation. Alcohol-free rinses are recommended instead.
C. Instruct the client on the use of esophageal speech. Esophageal speech is used in clients who have had laryngectomies, not those experiencing xerostomia. This intervention is unrelated to the client's current condition.
D. Provide humidification of the room air. Using a humidifier adds moisture to the environment, which helps relieve oral dryness and makes the client more comfortable, especially during sleep or in dry indoor climates.
