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. To assess pedal pulses, which arterial sites should the nurse palpate? (Select all that apply)

• A. Posterior tibial artery
• B. Radial artery
• C. External iliac artery
• D. Dorsalis pedis artery

Correct answer: D

Rationale: The correct answer is D: Dorsalis pedis artery. When assessing pedal pulses, the nurse should palpate the dorsalis pedis artery and the posterior tibial artery. The radial artery is located in the wrist and is not a site for assessing pedal pulses. The external iliac artery is not a correct site for assessing pedal pulses in the lower extremities, making it the correct answer.

3. A client with a history of peptic ulcer disease (PUD) is prescribed omeprazole (Prilosec). What is the primary action of this medication?

• A. Neutralizes stomach acid
• B. Reduces gastric acid production
• C. Forms a protective barrier over ulcers
• D. Increases gastric mucus production

Correct answer: B

Rationale: The correct answer is B: Reduces gastric acid production. Omeprazole is a proton pump inhibitor that works by reducing gastric acid production, thereby helping to heal ulcers. While neutralizing stomach acid is associated with antacids, forming a protective barrier over ulcers is more characteristic of medications like sucralfate. The action described in choice D, increasing gastric mucus production, is not the primary mechanism of action of omeprazole in treating peptic ulcer disease.

4. The healthcare provider plans to assess a newborn and check the infant's Moro reflex. What is the healthcare provider evaluating?

• A. Neurological integrity
• B. Renal functioning
• C. Thermoregulation
• D. Respiratory adequacy

Correct answer: A

Rationale: The Moro reflex is an instinctive response observed in newborns, indicating their neurological integrity. This reflex is evaluated by eliciting a startle response in the infant, involving the sudden extension and abduction of the limbs, followed by their retraction. This assessment helps in determining the proper functioning of the infant's nervous system and brain. Choices B, C, and D are incorrect as they do not relate to the evaluation of the Moro reflex. Renal functioning pertains to kidney function, thermoregulation refers to temperature control, and respiratory adequacy involves assessing breathing and oxygenation levels, none of which are evaluated through the Moro reflex.

5. The nurse is preparing to administer a subcutaneous injection of heparin. What is the correct angle of insertion?

• A. 15 degrees
• B. 30 degrees
• C. 45 degrees
• D. 90 degrees

Correct answer: C

Rationale: The correct angle of insertion for a subcutaneous injection, such as heparin, is 45 degrees. This angle is appropriate as it helps to ensure proper delivery of the medication into the subcutaneous tissue. Option A (15 degrees) is too shallow for a subcutaneous injection and may result in the medication being deposited into the muscle. Option B (30 degrees) is also too shallow for subcutaneous injections. Option D (90 degrees) is used for intramuscular injections, not subcutaneous injections.
