1. What is the most common cause of HHNS?

A. Insulin overdose
B. Removal of the adrenal gland
C. Undiagnosed, untreated hyperpituitarism
D. Undiagnosed, untreated diabetes mellitus

Correct answer: D

Rationale: The correct answer is D: Undiagnosed, untreated diabetes mellitus. Hyperosmolar hyperglycemic nonketotic syndrome (HHNS) is most commonly caused by undiagnosed and untreated diabetes mellitus. Insulin overdose (Choice A) is not a typical cause of HHNS; it is more related to hypoglycemia. Removal of the adrenal gland (Choice B) can lead to adrenal insufficiency but is not a common cause of HHNS. Undiagnosed, untreated hyperpituitarism (Choice C) is not a usual cause of HHNS; it is more related to pituitary hormone imbalances rather than hyperglycemia.

2. Which of the following is an example of a chronic disease?

A. Common cold
B. Influenza
C. Diabetes
D. Food poisoning

Correct answer: C

Rationale: Diabetes is classified as a chronic disease because it is a long-term condition that requires ongoing management. Choices A, B, and D, which are the common cold, influenza, and food poisoning, are acute illnesses that typically resolve on their own without long-lasting implications.

3. A nurse is orienting a newly licensed nurse about client confidentiality. Which of the following statements by the newly licensed nurse indicates an understanding of the teaching?

A. I can use another nurse's password as long as I log off after using the computer
B. I should encrypt personal health information when sending emails
C. I can post the client's vital signs in the client's room
D. I should discard personal health information documents in the trash before leaving the unit

Correct answer: B

Rationale: The correct answer is B because encrypting personal health information when sending emails is a crucial aspect of maintaining client confidentiality. This process ensures that sensitive information is protected during electronic communication. Choice A is incorrect as sharing passwords violates client confidentiality. Choice C is incorrect as posting client's vital signs breaches confidentiality. Choice D is incorrect as discarding personal health information in the trash can lead to unauthorized access.

4. A nurse is receiving a verbal prescription from the provider for a client who is experiencing increased pain. The nurse should transcribe which of the following prescriptions in the client's medical record?

A. Morphine sulfate 10 mg IV q 4 IV prn for pain
B. MS 10 mg IV every 4 8 prn for pain
C. MSO4 10 mg IVP q 4 8 prn for pain
D. Morphine sulfate 10.0 mg every 4 hours IV prn for pain

Correct answer: A

Rationale: The correct transcription is 'Morphine sulfate 10 mg IV q 4 IV prn for pain.' In choice A, 'Morphine sulfate 10 mg IV q 4 IV prn for pain' correctly indicates the medication, route (IV), frequency (every 4 hours), and administration as needed for pain control. Choice B is incorrect as 'MS' is not a standard abbreviation for Morphine Sulfate, and the frequency 'every 4 8' is not a valid time interval. Choice C is incorrect as 'MSO4' is not the standard abbreviation for Morphine Sulfate, and 'IVP' is not the standard route abbreviation for intravenous. Choice D is incorrect as it lacks clarity with '10.0 mg' instead of '10 mg,' and the frequency is given as 'every 4 hours' without specifying the route of administration.

5. A nurse in the emergency department is assessing a client who is unconscious following a motor-vehicle crash. The client requires immediate surgery. Which of the following actions should the nurse take?

A. Transport the client to the operating room without verifying informed consent
B. Ask the anesthesiologist to sign the consent
C. Obtain telephone consent from the facility administrator before the surgery
D. Delay the surgery until the nurse can obtain informed consent

Correct answer: A

Rationale: In emergency situations where a client is unconscious and requires immediate surgery, implied consent applies. Implied consent allows healthcare providers, including nurses, to proceed with necessary treatment or surgery without formally verifying informed consent. Choice A is correct because the priority in this scenario is to ensure the client receives timely medical intervention to address life-threatening conditions. Choices B, C, and D are incorrect because in emergencies, waiting to obtain formal consent can delay critical treatment, risking the client's health and well-being.
