Nursing Elites

1. While ambulating in the hallway following an appendectomy yesterday, a client complains of chest tightness and shortness of breath. Which action should the nurse implement first?

• A. Administer sublingual nitroglycerin
• B. Assist the client back to the room
• C. Have the client sit down in the hall
• D. Obtain a 12-lead electrocardiogram

Correct answer: C

Rationale: Having the client sit down in the hallway is the first action the nurse should implement. This is crucial to prevent further strain on the heart and to provide a safer environment for assessment and potential emergency intervention. Administering sublingual nitroglycerin (Choice A) may be appropriate later but should not precede ensuring the client's immediate safety. Assisting the client back to the room (Choice B) may not be advisable if the client is experiencing chest tightness and shortness of breath. Obtaining a 12-lead electrocardiogram (Choice D) is important but would not be the initial action to address the client's immediate symptoms.

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. An adult female client with type 1 diabetes mellitus is receiving NPH insulin 35 units in the morning. Which finding should the nurse document as evidence that the amount of insulin is inadequate?

• A. States that her feet are constantly cold and numb
• B. A wound on the ankle that starts to drain and becomes painful
• C. Consecutive evening serum glucose greater than 260 mg/dL
• D. Reports nausea in the morning but still able to eat breakfast

Correct answer: C

Rationale: The correct answer is C. Consistently high evening glucose levels indicate that the current insulin dosage is inadequate to maintain proper glucose control. Choice A is incorrect because cold and numb feet are more indicative of peripheral vascular disease rather than inadequate insulin dosage. Choice B describes a wound that may be related to poor circulation or neuropathy but not necessarily inadequate insulin dosage. Choice D suggests gastrointestinal issues that are not directly related to insulin dosage adequacy.

4. A client post-thyroidectomy is being monitored for signs of hypocalcemia. Which of the following symptoms should the nurse be most concerned about?

• A. Tingling in the hands and around the mouth.
• B. Nausea and vomiting.
• C. Constipation.
• D. Bradycardia.

Correct answer: A

Rationale: The correct answer is A: Tingling in the hands and around the mouth. This symptom is a classic sign of hypocalcemia, which can occur after thyroidectomy if the parathyroid glands were inadvertently damaged during surgery. Nausea and vomiting (Choice B) are not specific to hypocalcemia. Constipation (Choice C) is not a typical symptom of hypocalcemia. Bradycardia (Choice D) is more commonly associated with hypothyroidism rather than hypocalcemia.

5. Which type of cell is responsible for producing antibodies in the immune system?

• A. B lymphocytes
• B. T lymphocytes
• C. Macrophages
• D. Neutrophils

Correct answer: A

Rationale: The correct answer is A: B lymphocytes. B lymphocytes (B cells) are a crucial part of the adaptive immune system. They produce antibodies, which are proteins that specifically target and neutralize pathogens such as bacteria and viruses. T lymphocytes (choice B) are involved in cell-mediated immunity rather than antibody production. Macrophages (choice C) are phagocytic cells that engulf and digest pathogens but do not produce antibodies. Neutrophils (choice D) are a type of white blood cell that primarily function in the innate immune response by phagocytosing pathogens.
