Nursing Elites

1. A client has a prescription for a Transcutaneous Electrical Nerve Stimulator (TENS) unit for pain management during the postoperative period following a Lumbar Laminectomy. What information should the nurse reinforce about the action of this adjuvant pain modality?

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

Correct answer: A

Rationale: The correct answer is A. TENS units work by delivering small electrical impulses through the skin. These impulses are thought to close the 'gates of nerve conduction,' which can help in managing severe pain. Choice B is incorrect because the dulled pain perception does not occur in the cerebral cortex by the TENS unit. Choice C is incorrect as it describes a different method of pain management involving medication in the spinal canal. Choice D is incorrect because TENS does not work by distracting the client's focus on pain, but rather by altering pain perception through electrical impulses.

2. A client with a diagnosis of bipolar disorder is prescribed lithium. Which electrolyte imbalance should the nurse monitor for?

• A. Hyponatremia
• B. Hypokalemia
• C. Hypercalcemia
• D. Hypernatremia

Correct answer: A

Rationale: The correct answer is A: Hyponatremia. Lithium can affect sodium levels in the body, potentially leading to hyponatremia, which is a condition characterized by low sodium levels. This imbalance requires close monitoring as it can lead to symptoms such as confusion, weakness, and even seizures. Choices B, C, and D are incorrect because lithium is not primarily associated with causing hypokalemia, hypercalcemia, or hypernatremia. While these imbalances can occur in certain conditions or with other medications, the main electrolyte imbalance to monitor when a client is prescribed lithium is hyponatremia.

3. Which intervention is most effective in preventing the spread of infection in a healthcare setting?

• A. Wearing gloves
• B. Using hand sanitizer
• C. Practicing hand hygiene
• D. Disinfecting surfaces

Correct answer: C

Rationale: Practicing hand hygiene is the most effective measure to prevent the spread of infection in healthcare settings. While wearing gloves, using hand sanitizer, and disinfecting surfaces are important infection control measures, they are not as effective as proper hand hygiene. Hand hygiene, including handwashing with soap and water or using alcohol-based hand sanitizers, is crucial in preventing the transmission of pathogens from one person to another, making it the best choice among the options provided. Wearing gloves primarily protects the wearer and is not a substitute for hand hygiene. Using hand sanitizer is helpful but may not be as effective as proper handwashing. Disinfecting surfaces is important but does not address the direct transmission of pathogens through hand contact, which hand hygiene effectively prevents.

4. The healthcare provider is assessing a client who has just undergone a thyroidectomy. Which assessment finding is most concerning?

• A. Hoarseness of the voice
• B. Slight swelling at the incision site
• C. Tingling around the mouth
• D. Mild fever

Correct answer: C

Rationale: Tingling around the mouth is the most concerning finding as it may indicate hypocalcemia, a potential complication after thyroidectomy. Hoarseness of the voice is common due to surgical manipulation, slight swelling at the incision site is expected postoperatively, and mild fever can be a normal inflammatory response. Hypocalcemia after thyroidectomy can lead to serious complications and should be addressed promptly to prevent further issues.

5. During a routine prenatal visit, a nurse measures a client’s fundal height. The client is 26 weeks pregnant. What should the fundal height be?

• A. Approximately 26 cm
• B. Between 24 to 28 cm
• C. Above the umbilicus by two finger widths
• D. Below the xiphoid process

Correct answer: B

Rationale: The correct answer is B: Between 24 to 28 cm. Fundal height corresponds to the weeks of gestation, so at 26 weeks of pregnancy, the fundal height should range between 24 to 28 cm. This measurement is a quick way to assess fetal growth and amniotic fluid volume. Choice A is incorrect because fundal height may vary and not always match the exact weeks of pregnancy. Choice C, measuring above the umbilicus by two finger widths, is not a standard method for fundal height measurement. Choice D, below the xiphoid process, is too high and not relevant for assessing fundal height during pregnancy.
