1. 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.

2. A client has a prescription for a transcutaneous electrical nerve stimulator (TENS) unit for pain management during the postoperative period following a lumbar laminectomy. Which information should the PN reinforce about the action of the adjuvant pain modality?

• A. The discharge of electricity will distract the client's focus from the pain.
• B. An infusion of medication into the spinal canal will block pain perception.
• C. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus.
• D. A mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain.

Correct answer: D

Rationale: The TENS unit works by providing a mild electrical stimulus to the skin, which helps to 'close the gate' on pain signals, reducing the perception of pain. Choice A is incorrect because distraction is not the primary mechanism of action for TENS. Choice B is incorrect as it describes a different method of pain management involving medication infusion into the spinal canal. Choice C is incorrect as it inaccurately describes the location of pain perception modulation by the TENS unit.

3. At the end of a 12-hour shift, the PN observes the urine in a client's drainage bag as seen in the picture. Which action should the PN take next?

• A. Offer to administer a prescribed PRN analgesic
• B. Obtain a finger stick capillary glucose level
• C. Determine if the client's bladder feels distended
• D. Note the most recent white blood cell count

Correct answer: D

Rationale: Noting the white blood cell count is the most appropriate action in this situation. Changes in urine appearance could indicate infection, and assessing the white blood cell count helps in evaluating the possibility of infection. This is crucial for understanding the client's overall condition. The other options are not directly related to assessing infection based on urine appearance. Offering analgesics, checking glucose levels, or determining bladder distention may not address the underlying issue of a potential infection.

4. 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.

5. While assessing an older male client who takes psychotropic medications, the nurse observes uncontrollable hand movements and excessive blinking. Which information in the client's medical record should the nurse review?

• A. Prescription for lorazepam
• B. History of Parkinson's disease
• C. Screening for tardive dyskinesia
• D. Recent urine drug screen report

Correct answer: C

Rationale: The symptoms of uncontrollable hand movements and excessive blinking are indicative of tardive dyskinesia, a possible side effect of long-term use of psychotropic medications. Reviewing the screening for tardive dyskinesia is crucial to assess if these symptoms are related to the medication. Option A, the prescription for lorazepam, is less relevant as the focus should be on potential side effects rather than the specific medication. Option B, history of Parkinson's disease, is not directly related to the observed symptoms, which are more likely linked to medication side effects. Option D, recent urine drug screen report, is not as pertinent in this context compared to reviewing the screening for tardive dyskinesia.
