Nursing Elites

1. A twenty-one-year-old man suffered a concussion, and the MD ordered an MRI. The patient asks, 'Will they allow me to sit up during the MRI?' The correct response by the nurse should be:

• A. "I will have to talk to the doctor about letting you sit upright during the test."?
• B. "You will be positioned in the reverse Trendelenburg position to maximize the view of the brain."?
• C. "The radiologist will let you know."?
• D. "You will have to lie down on your back during the test."?

Correct answer: D

Rationale: The correct answer is to inform the patient that they will have to lie down on their back during the MRI. This positioning is necessary for the scan to obtain accurate images of the brain. Choice A is incorrect because the decision on the positioning during the MRI is typically determined by the imaging protocol and not subject to negotiation during the test. Choice B is incorrect as the reverse Trendelenburg position is not commonly used during MRI scans. Choice C is incorrect because the radiologist does not usually make decisions on patient positioning during the MRI; it is predetermined by the imaging requirements.

2. The client is admitted to the unit after a cholecystectomy. Montgomery straps are utilized with this client. The nurse is aware that Montgomery straps are utilized on this client because:

• A. The client is at risk for evisceration.
• B. The client will require frequent dressing changes.
• C. The straps provide support for drains that are inserted in the incision.
• D. No sutures or clips are used to secure the incision.

Correct answer: B

Rationale: Montgomery straps are used to secure dressings that require frequent changes due to the large amount of drainage usually present after a cholecystectomy. They are also beneficial for clients allergic to various types of tape. Answer A is incorrect as the client is not at higher risk of evisceration. Answer C is incorrect because Montgomery straps are not used to support drains. Answer D is incorrect as sutures or clips are typically used to secure the incision after gallbladder surgery, not Montgomery straps.

3. The chemotherapeutic DNA alkylating agents such as nitrogen mustards are effective because they:

• A. cross-link DNA strands with covalent bonds between alkyl groups on the drug and guanine bases on DNA.
• B. have few, if any, side effects.
• C. are used to treat multiple types of cancer.
• D. are cell-cycle-specific agents.

Correct answer: A

Rationale: Alkylating agents, such as nitrogen mustards, are effective chemotherapeutic agents because they cross-link DNA strands with covalent bonds between alkyl groups on the drug and guanine bases on DNA. This cross-linking interferes with DNA replication and transcription, leading to cell death. Choice B is incorrect because alkylating agents have numerous side effects, including alopecia, nausea, vomiting, and myelosuppression. Choice C is incorrect because while nitrogen mustards are used to treat multiple types of cancer like chronic lymphocytic leukemia, non-Hodgkin's lymphoma, and breast and ovarian cancer, their effectiveness is primarily due to DNA cross-linkage. Choice D is incorrect because alkylating agents are non-cell-cycle-specific agents, meaning they can act on cells in any phase of the cell cycle, not just on cells that are actively dividing.

4. Why is the intravenous route potentially the most dangerous route of drug administration?

• A. IV infiltration may occur.
• B. it allows for rapid administration of a drug.
• C. rapid administration of a drug can lead to toxicity
• D. it is the most commonly used route in hospitals.

Correct answer: C

Rationale: The correct answer is C: rapid administration of a drug can lead to toxicity. When a drug is administered intravenously, it has 100% bioavailability, entering the bloodstream immediately and increasing the risk of toxicity if not carefully monitored. While IV infiltration (choice A) can cause tissue damage, it is not typically life-threatening. Choice B is incorrect as the speed of administration is not the primary reason for the danger; it is the immediate and full dose reaching the bloodstream. Choice D is incorrect as the popularity of the route does not inherently make it more dangerous.

5. The client is being assessed for possible pernicious anemia. Which finding would support this diagnosis?

• A. A weight loss of 10 pounds in 2 weeks
• B. Complaints of numbness and tingling in the extremities
• C. A red, beefy tongue
• D. A hemoglobin level of 12.0 g/dL

Correct answer: C

Rationale: The correct answer is a red, beefy tongue, which is characteristic of pernicious anemia due to the atrophy of the papillae on the tongue. This finding is known as glossitis. A red, beefy tongue is a classic sign of pernicious anemia. Choice A, weight loss of 10 pounds in 2 weeks, is non-specific and not a typical finding in pernicious anemia. Choice B, complaints of numbness and tingling in the extremities, are more indicative of peripheral neuropathy, a common symptom of vitamin B12 deficiency, which can be seen in pernicious anemia. Choice D, a hemoglobin level of 12.0 g/dL, falls within the normal range and does not specifically point towards pernicious anemia, which is characterized by low hemoglobin levels due to impaired absorption of vitamin B12.
