What is the lowest fasting plasma glucose level suggestive of a diagnosis of DM?
- A. 90 mg/dl.
- B. 115 mg/dl.
- C. 126 mg/dl.
- D. 180 mg/dl.
Correct Answer: C
Rationale: A fasting plasma glucose level of 126 mg/dl or higher is diagnostic of diabetes mellitus. Choice A (90 mg/dl) is too low to indicate diabetes. Choice B (115 mg/dl) is also below the diagnostic threshold for diabetes. Choice D (180 mg/dl) is above the diagnostic threshold and would indicate uncontrolled diabetes, not the lowest level suggestive of a diagnosis.

Why have recent polls placed nursing as one of the most trusted professions?
- A. Nurses engage in lifelong learning.
- B. Nurses abide by a dress code.
- C. Nurses have the skills needed to care for diverse populations.
- D. Nurses must pass the NCLEX in order to obtain a license to practice.
Correct Answer: C
Rationale: Recent polls have identified nursing as one of the most trusted professions primarily because nurses possess the essential skills required to provide care to diverse populations. This includes cultural competence, empathy, effective communication, and clinical expertise. Choice A, engaging in lifelong learning, is indeed an important aspect of nursing practice; however, it is not the primary reason for the high level of trust placed in nurses. Choice B, abiding by a dress code, is a professional conduct issue and not directly linked to the trustworthiness of nurses. Choice D, passing the NCLEX exam for licensure, is a regulatory requirement and does not directly contribute to the trust placed in nurses by the public.
In a 29-year-old female client who is being successfully treated for Cushing's syndrome, nurse Lyzette would expect a decline in:
- A. Serum glucose level.
- B. Hair loss.
- C. Bone mineralization.
- D. Menstrual flow.
Correct Answer: A
Rationale: The correct answer is A: Serum glucose level. In Cushing's syndrome, there is excess cortisol production which can lead to hyperglycemia. Successful treatment of Cushing's syndrome aims to normalize cortisol levels, resulting in a decline in serum glucose levels. Choice B, hair loss, is not specifically associated with Cushing's syndrome or its treatment. Choice C, bone mineralization, is often compromised in Cushing's syndrome due to the effects of excess cortisol on bones; however, successful treatment would aim to improve bone health rather than decline it. Choice D, menstrual flow, is not directly linked to Cushing's syndrome or its treatment, so a decline in menstrual flow would not be an expected outcome of successful treatment.
A client with diabetes mellitus is receiving an oral antidiabetic medication. The nurse should monitor for which of the following adverse effects?
- A. Weight gain
- B. Hypoglycemia
- C. Hyperglycemia
- D. Bradycardia
Correct Answer: B
Rationale: The correct answer is B: Hypoglycemia. When a client with diabetes mellitus is taking oral antidiabetic medication, the nurse should closely monitor for hypoglycemia, which is a common adverse effect. Hypoglycemia occurs when the blood sugar levels drop below normal range, leading to symptoms like confusion, shakiness, and sweating. Weight gain (Choice A) is not a typical adverse effect of oral antidiabetic medications. Hyperglycemia (Choice C) is the opposite of the desired effect of antidiabetic medications, which aim to lower blood sugar levels. Bradycardia (Choice D) is not directly associated with oral antidiabetic medications; it refers to a slow heart rate.
During the physical examination, Nurse Noah expects to assess which sign in a female client with a serum calcium level of 7.2 mg/dl?
- A. Trousseau's sign
- B. Homans' sign
- C. Hegar's sign
- D. Goodell's sign
Correct Answer: A
Rationale: Trousseau's sign is a clinical indicator of hypocalcemia, characterized by carpal spasm when a blood pressure cuff is inflated above systolic pressure and maintained for a few minutes. This occurs due to increased neuromuscular irritability associated with low serum calcium levels. Homans' sign is used to assess for deep vein thrombosis and involves calf pain upon dorsiflexion of the foot. Hegar's sign is a softening of the lower uterine segment seen in pregnancy, while Goodell's sign is softening of the cervix also seen in pregnancy. Therefore, in this scenario, the correct assessment related to hypocalcemia would be Trousseau's sign.
A client with type 1 DM is taught to take NPH and regular insulin every morning. The nurse should provide which instructions to the client?
- A. Take the NPH insulin first, then the regular insulin.
- B. Take the regular insulin first, then the NPH insulin.
- C. It does not matter which insulin is drawn up first.
- D. Contact the healthcare provider if the order for insulin is unclear.
Correct Answer: B
Rationale: The correct answer is to take the regular insulin first, then the NPH insulin. Regular insulin should be drawn up before NPH insulin to prevent contamination of the regular insulin vial with the longer-acting insulin. Choice A is incorrect as it suggests taking the NPH insulin first, which is not the recommended practice. Choice C is incorrect because the order of drawing up insulin does matter to prevent contamination. Choice D is not the most appropriate action in this scenario, as the nurse should provide clear instructions to the client based on best practices.
