Nursing Elites

1. You are caring for a patient who has no cognitive functioning but only basic human functions such as opening the eyes and the sleep-wake cycle. What level of consciousness does this patient have?

• A. Obtunded
• B. A persistent vegetative state
• C. Locked-in syndrome
• D. Brain death

Correct answer: B

Rationale: A persistent vegetative state is characterized by the absence of cognitive functioning while basic human functions like the sleep-wake cycle are retained. In this state, the patient shows reflex movements and basic responses to stimuli but lacks awareness or higher mental functions. Choices A, C, and D are incorrect because: A) Obtunded refers to a decreased level of consciousness, not the absence of cognitive functioning. C) Locked-in syndrome is a condition where the patient is aware and awake but cannot move or communicate due to complete paralysis of nearly all voluntary muscles except for vertical eye movements and blinking. D) Brain death is the irreversible cessation of all brain activity, including the brainstem, leading to the loss of all functions of the brain.

2. A patient's serum potassium level is 2.2 mEq/L. Which nursing action is the highest priority for this patient?

• A. Start oxygen at 2 L/min
• B. Initiate cardiac monitoring
• C. Initiate seizure precautions
• D. Keep the patient on bed rest

Correct answer: B

Rationale: The correct answer is to initiate cardiac monitoring. Severe hypokalemia can lead to life-threatening arrhythmias, making cardiac monitoring the priority to detect and manage any cardiac complications. Starting oxygen, seizure precautions, or bed rest are not the immediate priority actions for severe hypokalemia.

3. Dr. Shrunk orders intravenous (IV) insulin for Rita, a client with a blood sugar of 563. Nurse AJ administers insulin lispro (Humalog) intravenously (IV). What does the best evaluation of the nurse reveal? Select one that does not apply.

• A. The nurse could have given the insulin subcutaneously.
• B. The nurse did not have to contact the physician.
• C. The nurse should have used regular insulin (Humulin R).
• D. The nurse used the correct insulin.

Correct answer: C

Rationale: The best evaluation of the nurse reveals that she should have used regular insulin (Humulin R) for IV administration. Regular insulin is the only insulin approved for intravenous administration due to its pharmacokinetic properties. Insulin lispro (Humalog) is not suitable for IV use. Choice A is incorrect because giving insulin intravenously is necessary in this case of high blood sugar. Choice B is incorrect because administering a different insulin without consulting the physician is not appropriate. Choice D is incorrect because the nurse used the incorrect insulin, which could pose risks to the client's health.

4. Which insulin has the most rapid onset of action?

• A. Lente
• B. Lispro
• C. Ultralente
• D. Humulin N

Correct answer: B

Rationale: Lispro insulin has the most rapid onset of action among the options provided. It is a rapid-acting insulin analog that is designed to control postprandial hyperglycemia effectively. Lente insulin (Choice A) and Ultralente insulin (Choice C) are intermediate-acting insulins, which have a slower onset of action compared to Lispro. Humulin N (Choice D) is a neutral protamine Hagedorn (NPH) insulin, which is an intermediate-acting insulin, not rapid-acting like Lispro. Therefore, the correct choice is Lispro.

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.
