Nursing Elites

1. The client with high blood pressure is being taught by the nurse to avoid adding salt during cooking. What effect does sodium have on blood pressure?

• A. It decreases the viscosity of blood
• B. It leads to increased fluid retention
• C. It causes vasoconstriction of the blood vessels
• D. It enhances the excretion of potassium

Correct answer: C

Rationale: The correct answer is C: 'It causes vasoconstriction of the blood vessels.' Sodium can lead to vasoconstriction, which narrows the blood vessels, increasing resistance to blood flow and subsequently raising blood pressure. Choices A, B, and D are incorrect. Sodium does not decrease blood viscosity, but it can lead to fluid retention, which increases blood volume and pressure. It does not enhance the excretion of potassium; instead, high sodium intake can lead to potassium excretion by the kidneys.

2. 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.

3. When assisting a client to obtain a sputum specimen, the nurse observes the client cough and spit a large amount of frothy saliva in the specimen collection cup. What action should the nurse implement next?

• A. Advise the client that suctioning will be used to obtain another specimen
• B. Re-instruct the client in coughing techniques to obtain another specimen
• C. Provide the client a glass of water and mouthwash to rinse the mouth
• D. Label the container and place the container in a biohazard transport bag

Correct answer: C

Rationale: After observing the client cough and produce frothy saliva in the collection cup, the nurse should provide the client with a glass of water and mouthwash to rinse the mouth. This action helps clear the mouth of contaminants, ensuring a more accurate sputum specimen for diagnostic testing. Option A is incorrect because suctioning is not the appropriate next step in this situation. Option B is unnecessary as re-instructing the client in coughing techniques may not address the immediate issue of contaminated saliva in the specimen. Option D is premature since labeling and transporting the container should only be done after obtaining a valid specimen.

4. 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.

5. The nurse is providing discharge instructions to a client who had a laparoscopic cholecystectomy. What should the nurse include in the teaching?

• A. Avoid driving for at least 2 weeks
• B. Resume a low-fat diet
• C. Remove the bandages from the incision after 24 hours
• D. Expect significant pain for the first week

Correct answer: C

Rationale: The correct answer is C: 'Remove the bandages from the incision after 24 hours.' Prompt removal of bandages after 24 hours promotes proper wound healing and reduces the risk of infection. Choice A is incorrect because avoiding driving for 2 weeks may not be universally necessary post-cholecystectomy. Choice B is incorrect because while a low-fat diet is recommended after surgery, it is not directly related to incision care. Choice D is incorrect because while pain is common post-surgery, stating 'significant pain for the first week' may not apply to all patients, potentially causing unnecessary anxiety.
