1. Which of the following represents a normal serum potassium level?

• A. 1.5 mEq/L
• B. 3.0 mEq/L
• C. 4.0 mEq/L
• D. 6.0 mEq/L

Correct answer: C

Rationale: The correct answer is 4.0 mEq/L. Normal serum potassium levels typically range from 3.5-5.5 mEq/L. Choice A (1.5 mEq/L) is below the normal range, Choice B (3.0 mEq/L) is also below the normal range, and Choice D (6.0 mEq/L) is above the normal range. Therefore, the only option within the normal range is Choice C (4.0 mEq/L).

2. In an emergency situation where a client is unconscious and requires immediate surgery, what action is necessary with regard to informed consent?

• A. The healthcare team will proceed with the surgery as consent is not needed in emergencies.
• B. The healthcare team will wait until the client's family can be contacted for consent.
• C. The healthcare team will contact the hospital clergy to provide informed consent.
• D. The healthcare team will obtain consent from the client's legal guardian before proceeding.

Correct answer: A

Rationale: In emergency situations where obtaining consent is not possible due to the client's condition, healthcare providers are allowed to perform life-saving procedures without informed consent. It is assumed that the client would want to receive necessary treatment to save their life. Therefore, the correct action is for the healthcare team to proceed with the surgery as consent is not needed. Waiting to contact the client's family for consent can delay life-saving treatment, risking the client's life. Contacting the hospital clergy for consent is unnecessary and can cause further delays. Obtaining consent from the client's legal guardian is not feasible in this critical situation and may lead to a delay in providing essential care.

3. Following an automobile accident that caused a head injury to an adult client, the nurse observes that the client sleeps for long periods of time. The nurse determines that the client has experienced injury to the:

• A. hypothalamus.
• B. thalamus.
• C. cortex.
• D. medulla.

Correct answer: A

Rationale: The hypothalamus is responsible for regulating sleep patterns among other functions. Injury to the hypothalamus can disrupt the sleep-wake cycle, leading to excessive sleepiness or changes in sleep patterns. Choices B, C, and D are incorrect as they do not primarily control sleep regulation. The thalamus is involved in relaying sensory information, the cortex is responsible for higher brain functions, and the medulla controls vital functions such as heartbeat and breathing.

4. When a physician removes a chest tube, which type of dressing is recommended to be placed over the site?

• A. transparent dressing
• B. colloidal dressing
• C. petrolatum gauze
• D. nonadherent dressing

Correct answer: C

Rationale: Petrolatum gauze is recommended to be placed over the site when a physician removes a chest tube because it forms an airtight seal, helping prevent air from entering the pleural space. This airtight seal is crucial to avoid complications such as a pneumothorax. Transparent dressing is not ideal for this purpose as it may not provide a sufficient seal due to its design. Colloidal dressing and nonadherent dressing are also not suitable for chest tube removal sites as they do not offer the same level of protection against air leakage and may not provide the necessary sealing properties.

5. In a community hospital, a nurse is employed as a staff nurse and is supervised by a nurse manager. The nurse understands that in this position, the term authority most appropriately refers to which description?

• A. Accepting responsibility for the actions of others
• B. The official power to ensure that an organizational decision is enforced
• C. Bearing the legal responsibility for others' performance of tasks
• D. Taking responsibility for what staff members do

Correct answer: B

Rationale: The term authority refers to the official power of an individual to approve or command an action or to ensure that a decision is enforced. In the context of the nurse's position supervised by a nurse manager, having authority means having the official power to ensure that organizational decisions are carried out. Choice A, accepting responsibility for the actions of others, is more related to accountability rather than authority. Choice C, bearing the legal responsibility for others' performance of tasks, is more about legal liability rather than authority. Choice D, taking responsibility for what staff members do, is similar to choice A and is more about accountability rather than having the official power to enforce decisions. Therefore, the correct answer is B as it directly relates to the concept of authority in the context described.
