The nurse is assessing a client with hyperkalemia. Which finding is consistent with this electrolyte imbalance?

A. Muscle weakness

B. Decreased deep tendon reflexes

C. Constipation

D. Hypotension

Correct Answer: A
Rationale: Muscle weakness is a common finding in clients with hyperkalemia. Hyperkalemia can lead to muscle weakness due to the effect of high potassium levels on muscle function. Decreased deep tendon reflexes (Choice B) are not typically associated with hyperkalemia; instead, hyperreflexia or increased reflexes may be observed. Constipation (Choice C) is not a common symptom of hyperkalemia. Hypotension (Choice D) is also not a typical finding in hyperkalemia; instead, hypertension or normal blood pressure may be present.

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.

During the assessment of a client who has suffered a stroke, what finding would indicate a complication?

• A. Difficulty swallowing
• B. A slight headache
• C. High blood pressure
• D. Muscle weakness on one side

Correct Answer: A
Rationale: Difficulty swallowing (dysphagia) can indicate complications such as aspiration risk, which is common after a stroke due to impaired swallowing reflexes. It poses a serious threat to the client's respiratory system. Options B, C, and D are less likely to indicate immediate complications post-stroke. A slight headache is a common complaint and may not necessarily indicate a complication. High blood pressure is a known risk factor for strokes but may not be an immediate post-stroke complication unless it is severely elevated. Muscle weakness on one side is a common sign of stroke but may not directly indicate a new complication.

A client with gastroesophageal reflux disease (GERD) is being taught about dietary modifications. What should be emphasized?

• A. Avoiding spicy and fatty foods
• B. Eating small, frequent meals
• C. Avoiding meals before bedtime
• D. All of the above

Correct Answer: D
Rationale: In managing GERD, dietary modifications play a significant role. Avoiding spicy and fatty foods helps reduce irritation, while eating small, frequent meals prevents overeating, which can trigger reflux. Avoiding meals before bedtime allows for better digestion and reduces the likelihood of acid reflux during the night. Therefore, all of the options (A, B, and C) are crucial in managing GERD symptoms, making choice D the correct answer.

Which client will benefit most from the application of pneumatic compression devices to the lower extremities? The client who

• A. is immobile on prescribed bedrest.
• B. has pressure ulcers on several toes.
• C. has diminished pedal pulse volume.
• D. is confused and trying to climb out of bed.

Correct Answer: A
Rationale: The correct answer is A. Pneumatic compression devices are most beneficial for immobile clients on prescribed bedrest to prevent deep vein thrombosis. Applying these devices helps in promoting circulation and preventing blood clots. Choices B, C, and D do not specifically relate to the primary indication for pneumatic compression devices, making them incorrect. Pressure ulcers, diminished pedal pulse volume, and confusion with climbing out of bed may require different interventions or treatments.
