An adolescent who was diagnosed with type 1 diabetes mellitus at the age of 9, is admitted to the hospital in diabetic ketoacidosis. Which occurrence is the most likely cause of the ketoacidosis?

Skipped eating lunch.

Incorrectly administered too much insulin.

Had a cold and ear infection for the past two days.

Ate an extra peanut butter sandwich before gym class.

None

Answer and Explanation

The Correct Answer is C

A. Skipped eating lunch would more likely cause hypoglycemia rather than diabetic ketoacidosis (DKA). When a person with type 1 diabetes skips a meal but still takes insulin, blood glucose levels drop, leading to hypoglycemia, not the elevated glucose and ketone production seen in DKA.

B. Incorrectly administered too much insulin would also result in hypoglycemia rather than DKA. Administering excessive insulin causes blood glucose levels to fall too low, which does not trigger the fat breakdown and ketone production that characterize DKA.

C. Had a cold and ear infection for the past two days is the most likely cause of diabetic ketoacidosis. Illness and infection cause the body to release stress hormones such as cortisol and adrenaline, which increase blood glucose levels and counteract insulin. In type 1 diabetes, insufficient insulin leads to hyperglycemia, fat breakdown for energy, and the production of ketones, resulting in DKA.

D. Ate an extra peanut butter sandwich before gym class would not cause DKA. Consuming extra food may raise blood glucose temporarily, but it would not lead to the severe insulin deficiency and ketone production seen in DKA, especially if the adolescent took insulin as prescribed.

Correct Answer is C

Explanation

A) Incorrect- reapplying a sterile non-adhesive dressing is not enough to address the infection.

The nurse should also clean the wound, apply topical antimicrobial agents, and change the dressing regularly.
B) Incorrect- limiting visitors to immediate family only is not a sufficient infection control measure. The nurse should also use standard precautions, such as wearing gloves, gowns, masks,
and eye protection, and educate the visitors about hand hygiene and proper disposal of contaminated items.
C) Correct- Administering prescribed antibiotics is the most important action because it can help treat the infection and prevent it from spreading to other parts of the body or to other people. MRSA is resistant to many common antibiotics, so it is essential to follow the prescription and monitor the client's response.
D) Incorrect- requesting a nutrition consult is not a priority action. While nutrition is important for wound healing, it does not directly affect the infection. The nurse should first administer antibiotics and then assess the client's nutritional status and needs.

A. “Come into the recreation area. We have your favorite card game and I will play it with you." B. "Why do you want to stay in your room today?” C. "I know you are sad about not seeing your family as often, but they are visiting as much as they can.” D. d “May I sit with you for a while?"

Correct Answer is D

Explanation

d. “May I sit with you for a while?"

This comment shows empathy, respect, and support for the client, without being intrusive or judgmental. The PN acknowledges the client's feelings and oﬀers companionship, which can help reduce isolation and loneliness.

The other options are not correct because:

This comment may be perceived as coercive or dismissive of the client's feelings, as it tries to persuade the client to do something he does not want to do or enjoy.
This comment may be perceived as accusatory or interrogatory, as it questions the client's decision or motive for staying in his room.
This comment may be perceived as minimizing or invalidating the client's feelings, as it implies that the client should not be sad or that his family is doing enough for him.
