What is the primary cause of diabetic ketoacidosis (DKA)?
- A. Insulin deficiency
- B. Overhydration
- C. Excess carbohydrate intake
- D. Excess insulin
Correct Answer: A
Rationale: The correct answer is A: Insulin deficiency. Diabetic ketoacidosis occurs due to a severe lack of insulin, causing the body to break down fat for energy, leading to the production of ketones and acidification of the blood. Option B, Overhydration, is incorrect as DKA is characterized by dehydration rather than overhydration. Option C, Excess carbohydrate intake, is incorrect because while high blood sugar levels can contribute to DKA, the primary cause is insulin deficiency. Option D, Excess insulin, is also incorrect as DKA is not caused by an excess of insulin but rather by a lack of it.

While caring for a client with a new tracheostomy, the nurse notices that the client is attempting to speak but is unable to. What should the nurse explain to the client regarding their inability to speak?
- A. Speaking is not possible because the tracheostomy tube blocks the vocal cords.
- B. The tracheostomy tube prevents air from reaching the vocal cords, making speech difficult.
- C. The client will regain the ability to speak once the tracheostomy tube is removed.
- D. The tracheostomy tube must be replaced with a speaking valve for the client to speak.
Correct Answer: B
Rationale: The correct answer is B. The tracheostomy tube bypasses the vocal cords, preventing air from reaching them, which is necessary for speech. This makes speaking difficult but not impossible. Removing the tracheostomy tube does not automatically restore the ability to speak (choice C). While a speaking valve can be added later to allow speech, initially, the tracheostomy tube itself hinders air from reaching the vocal cords, making speech difficult (choice D is incorrect). Choice A is incorrect as the tracheostomy tube does not block the vocal cords directly; instead, it prevents air from reaching them.
The PN observes a UAP preparing to exit a client's room. The UAP's hands appear visibly soiled as the UAP uses a hand rub for 19 seconds to cleanse the hands. Which action should the PN take?
- A. Confirm that the UAP completed hand hygiene correctly
- B. Instruct the UAP to wash the hands for one minute
- C. Ask the UAP why the hands were so obviously soiled
- D. Advise the UAP to use the hand rub for 30 seconds
Correct Answer: D
Rationale: When hands are visibly soiled, they should be washed with soap and water for at least 20 seconds. However, when using hand rub, it should be applied for at least 30 seconds to be effective. In this scenario, the UAP's hands were visibly soiled, indicating the need for thorough cleaning. Advising the UAP to use the hand rub for 30 seconds is essential to ensure proper hand hygiene and reduce the risk of spreading infection. Choices A, B, and C are incorrect because confirming completion of hand hygiene, instructing to wash for one minute, or asking why the hands were soiled do not address the immediate need for proper hand hygiene in the given situation.
The HCP gives a pregnant woman a prescription for one prenatal vitamin with iron daily and tells her that she needs to increase foods in her diet because her hemoglobin is 8.2 grams/dL. When a list of iron-rich foods is given to the client, she tells the PN that she is a vegetarian and does not eat anything that "bleeds." Which instruction should the PN provide?
- A. All below
- B. Increase green leafy vegetables in the diet
- C. Oatmeal is a good choice for breakfast
- D. Add lentils and black beans to soup
Correct Answer: A
Rationale: Vegetarians can increase their iron intake through plant-based sources such as green leafy vegetables, oatmeal, and legumes, which are rich in iron.
A client is post-operative day one following a colostomy surgery. The nurse notices the stoma is dark purple. What is the most appropriate action?
- A. Document the finding and continue to monitor.
- B. Apply warm compresses to the stoma.
- C. Notify the healthcare provider immediately.
- D. Encourage the client to ambulate.
Correct Answer: C
Rationale: A dark purple stoma may indicate compromised blood flow to the stoma, which is an emergency. Immediate notification of the healthcare provider is necessary to prevent further complications. Simply documenting and monitoring the finding (Choice A) could lead to delays in addressing a potentially serious issue. Applying warm compresses to the stoma (Choice B) may not address the underlying cause of the dark purple color. Encouraging the client to ambulate (Choice D) is not the priority when a compromised blood flow to the stoma is suspected.
When caring for a child with sickle cell disease, the PN expects that the child will most likely describe which symptom when experiencing a sickle cell crisis?
- A. Decreased hemoglobin
- B. Joint pain
- C. Fatigue
- D. Infection
Correct Answer: B
Rationale: During a sickle cell crisis, a child with sickle cell disease is most likely to describe joint pain. Sickle cell disease leads to the blockage of blood flow by sickled red blood cells, causing ischemia and pain, often felt in the joints and other body parts. Fatigue (choice C) is a nonspecific symptom that can occur in various conditions but is not a characteristic symptom of a sickle cell crisis. While decreased hemoglobin (choice A) can be observed in sickle cell disease, it is not a symptom typically described by a child during a sickle cell crisis. Infection (choice D) can trigger a sickle cell crisis but is not the symptom most likely to be described by the child during the crisis.
