Nursing Elites

1. A dispersion consists of a solute dispersed through a dispersing vehicle. Which of the following dispersions is a liquid for topical application that contains insoluble solids or liquids?

• A. Ointment
• B. Lotion
• C. Paste
• D. Gel

Correct answer: B

Rationale: The correct answer is B, 'Lotion.' A lotion is a liquid dispersion that contains insoluble solids or liquids for topical application. Ointments are more semi-solid and occlusive, pastes are thicker and contain higher concentrations of solids, and gels have a jelly-like consistency due to their three-dimensional network structure. Therefore, among the options, a lotion is the most suitable choice for containing insoluble solids or liquids for topical application.

2. Which task could the nurse safely delegate to the UAP?

• A. Oral feeding of a two-year-old child after application of a hip spica cast
• B. Assessment of the placement and patency of an NG tube
• C. Participation in staff rounds to record notes regarding client goals
• D. Evaluation of a client's incisional pain following narcotic administration

Correct answer: A

Rationale: The correct answer is A because oral feeding of a stable child is a task that can be safely delegated to a UAP. This task does not require nursing assessment or clinical judgment. Choice B involves assessment, which requires the nurse's clinical judgment. Choice C involves recording client goals during staff rounds, which may require interpretation and understanding of the goals set. Choice D involves evaluating a client's pain following medication administration, which requires assessment and clinical judgment by a nurse.

3. What is the primary role of the sinoatrial (SA) node in the heart?

• A. Pacemaker of the heart
• B. Blood pressure regulation
• C. Electrical conduction delay
• D. Stimulating muscle contraction

Correct answer: A

Rationale: The correct answer is A: Pacemaker of the heart. The SA node, known as the natural pacemaker, initiates the electrical impulses that set the rhythm for the heartbeat. It is responsible for coordinating the heart's contractions by generating electrical signals at regular intervals. Choice B is incorrect as the SA node's primary function is not related to blood pressure regulation. Choice C is incorrect as the SA node does not cause electrical conduction delay but rather initiates and conducts the electrical impulses. Choice D is incorrect as the SA node does not directly stimulate muscle contraction but rather initiates the electrical events that lead to muscle contraction.

4. At what age does a 9-year-old child typically lose which of the following teeth?

• A. Central incisor
• B. Second molar
• C. Lateral incisor
• D. Cuspid

Correct answer: A

Rationale: A 9-year-old child typically loses their central incisors, not the lateral incisors or second molars. The central incisors are usually among the first teeth that children lose around 6 to 7 years of age, as part of the natural process of shedding primary teeth to make way for permanent teeth. The second molars and cuspids are typically lost later in the mixed dentition phase. Therefore, option A, 'Central incisor,' is the correct answer.

5. The UAP is caring for a male resident of a long-term care facility who has an external urinary catheter. Which finding should the PN instruct the UAP to report immediately?

• A. Swollen and discolored penile shaft
• B. Prepuce extends over the head of the penis
• C. Leaking urine around the top of the catheter
• D. Moist and excoriated perineal skin folds

Correct answer: A

Rationale: The correct answer is A: Swollen and discolored penile shaft. Swelling and discoloration of the penile shaft may indicate an infection or other complications requiring immediate attention. Prompt reporting allows for timely intervention to prevent further harm to the client. Choice B is incorrect because the prepuce extending over the head of the penis is not an urgent issue. Choice C, leaking urine around the catheter, may require intervention but is not as urgent as the swelling and discoloration described in choice A. Choice D, moist and excoriated perineal skin folds, also needs attention but is not as concerning as the potential complications indicated by the findings in choice A.
