A nurse is preparing to administer 5 units of regular insulin and 20 units of NPH insulin to a client who has type 1 diabetes mellitus. Which of the following actions should the nurse take first?
Inject 20 units of air into the vial of NPH insulin.
Inject 5 units of air into the vial of regular insulin.
Withdraw 20 units of NPH insulin from the vial.
Withdraw 5 units of regular insulin from the vial.
The Correct Answer is A
Answer: (A) Inject 20 units of air into the vial of NPH insulin.
Rationale:
A) Inject 20 units of air into the vial of NPH insulin:
Injecting air into the vial of NPH insulin is the first step to prevent creating a vacuum, which could make it difficult to withdraw the insulin later. The nurse must inject the corresponding amount of air for the dose needed, ensuring that the insulin can be withdrawn smoothly and accurately without bubbles, which could affect the dose.
B) Inject 5 units of air into the vial of regular insulin:
Injecting air into the regular insulin vial is also necessary before withdrawing the insulin, but it should be done after injecting air into the NPH vial. This sequence ensures that no NPH insulin contaminates the regular insulin vial when the nurse withdraws the doses later.
C) Withdraw 20 units of NPH insulin from the vial:
Withdrawing NPH insulin should be done after air is injected into both vials and after the regular insulin has been drawn up. This sequence prevents the mixing of the two types of insulin and ensures accurate dosing, which is crucial for maintaining the correct blood glucose levels.
D) Withdraw 5 units of regular insulin from the vial:
Withdrawing regular insulin is critical to do before the NPH insulin to prevent contamination of the regular insulin with NPH, which could alter the onset and peak times of the regular insulin. However, it should follow the steps of injecting air into both vials, starting with the NPH vial.

Correct Answer is D
Explanation
Answer: (D) Refrigerate the specimen until the time of transport to the laboratory
Rationale:
A) Collect 2 ml of sputum in an emesis basin: While it is important to collect an adequate volume of sputum, using an emesis basin is inappropriate for collecting a specimen for culture and sensitivity. Sputum must be collected in a sterile container to avoid contamination, ensuring the accuracy of the culture results.
B) Instruct the client to rinse with an antiseptic mouthwash prior to specimen collection: Using an antiseptic mouthwash before collecting a sputum specimen is not recommended, as it could contaminate the sample with antiseptic agents, potentially affecting the growth of microorganisms in the culture. The client should rinse with plain water instead.
C) Swab the oropharynx with a sterile swab: Swabbing the oropharynx is more appropriate for collecting a throat culture rather than a sputum specimen. Sputum collection requires the client to expectorate mucus from the lower respiratory tract, not from the oropharynx, to obtain an accurate sample for culture and sensitivity.
D) Refrigerate the specimen until the time of transport to the laboratory: Refrigerating the sputum specimen is crucial to preserve the integrity of the sample and inhibit the growth of contaminants before it is transported to the laboratory. This action helps ensure that the results of the culture and sensitivity test are accurate.
Correct Answer is B
Explanation
b. Give directions using simple phrases.
The correct answer is b. Give directions using simple phrases.
Explanation:
When assisting with the plan of care for a client with Alzheimer's disease, it is important to consider their cognitive impairments and provide appropriate interventions. Giving directions using simple phrases is recommended because it helps the client beter understand and follow instructions. Complex or lengthy directions can be confusing and overwhelming for individuals with Alzheimer's disease. Using clear and concise language can enhance communication and facilitate the client's ability to engage in activities of daily living.
Explanation for the other options:
a. Encourage the client to talk about current events: While social interaction and engagement are beneficial for clients with Alzheimer's disease, their ability to comprehend and discuss current events may be limited due to cognitive impairments. It is important to adapt communication to the client's cognitive abilities and interests.
c. Orient the client to time and place twice per day: Frequent orientation to time and place can be helpful for clients with Alzheimer's disease, but the specific frequency should be based on the individual's needs and preferences. Some individuals may require more frequent orientation, while others may find it overwhelming. The plan of care should be individualized to address the client's specific needs.
d. Rotate assistive personnel to help the client with ADLs: Consistency and familiarity are important for individuals with Alzheimer's disease. Rotating assistive personnel frequently may disrupt the client's routine and cause increased confusion and agitation. Whenever possible, it is best to maintain a consistent caregiving team to provide familiarity and establish a therapeutic relationship with the client.
In summary, giving directions using simple phrases is an appropriate action when assisting with the plan of care for a client with Alzheimer's disease. This approach promotes effective communication and enhances the client's ability to understand and follow instructions.
