Nursing Elites

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. Under what circumstances can an individual receive medical care without giving informed consent?

• A. when the durable power of attorney for health care is not available
• B. in an emergency, life-or-death situation
• C. when the physician is not available for discussion with the client
• D. when they (clients) are not able to speak for themselves

Correct answer: B

Rationale: An individual may receive medical care without giving informed consent in an emergency, life-or-death situation. This exception allows healthcare providers to provide immediate treatment to save a person's life or prevent serious harm when time is of the essence. Choices A, C, and D are incorrect because in all other situations, informed consent is required. The durable power of attorney for health care should be involved if available, the physician should have a discussion with the client in non-life-threatening situations, and in cases where clients are unable to speak for themselves, their designated representative or responsible party should be involved in the consent process.

3. When the healthcare provider is determining the appropriate size of an oropharyngeal airway to insert, what part of a client's body should they measure?

• A. corner of the mouth to the tragus of the ear
• B. corner of the eye to the top of the ear
• C. tip of the chin to the sternum
• D. tip of the nose to the earlobe

Correct answer: A

Rationale: When selecting the correct size of an oropharyngeal airway, the healthcare provider should measure from the corner of the client's mouth to the tragus of the ear. This measurement ensures that the airway is the appropriate length to maintain a clear air passage for exchange. Measuring from the corner of the eye to the top of the ear (Choice B) is inaccurate and not a standard measurement for selecting the size of an oropharyngeal airway. Measuring from the tip of the chin to the sternum (Choice C) is irrelevant to determining the correct size of the airway. Similarly, measuring from the tip of the nose to the earlobe (Choice D) is also incorrect and does not provide the necessary measurement for selecting an oropharyngeal airway size.

4. The nurse is teaching a client about erythema infectiosum. Which of the following factors is not correct?

• A. There is no rash.
• B. The disorder is uncommon in adults.
• C. There is no fever.
• D. There is sometimes a 'slapped face' appearance.

Correct answer: B

Rationale: The correct answer is B: 'The disorder is uncommon in adults.' Erythema infectiosum, also known as Fifth's disease, is more common in children than in adults. It typically presents with a rash on the face that gives a 'slapped cheek' or 'slapped face' appearance. Fever may be present, and there is a characteristic rash associated with the condition. Therefore, the statement 'The disorder is uncommon in adults' is incorrect, making it the correct answer. The other statements are true regarding erythema infectiosum, making them incorrect choices. There is indeed a rash associated with erythema infectiosum, which can be a prominent feature. Fever may also be present in individuals with this condition. Additionally, the 'slapped face' appearance is a classic characteristic of erythema infectiosum.

5. A client with major head trauma is receiving bolus enteral feeding. The most important nursing order for this client is:

• A. measure intake and output.
• B. check albumin levels.
• C. monitor glucose levels.
• D. increase enteral feeding.

Correct answer: A

Rationale: The correct action for a client with major head trauma receiving bolus enteral feeding is to measure intake and output (I&O). Enteral feedings are hyperosmotic agents that can cause fluid shifts. Monitoring I&O is crucial to assess fluid balance, ensuring that input matches output. Checking albumin levels (choice B) is important for assessing nutritional status but is not the immediate priority in this situation. Monitoring glucose levels (choice C) is also important but not as critical as measuring I&O in this context. Increasing enteral feeding (choice D) should only be done based on a healthcare provider's order after assessing the patient's condition, not as the most important nursing order at this time.
