Nursing Elites

1. Social support systems include all of the following except:

• A. call-in help lines
• B. emotional assistance provided by others
• C. community support groups
• D. use of coping skills and verbalization for anger management

Correct answer: D

Rationale: The correct answer is the use of coping skills and verbalization for anger management. Social support systems involve external sources of support from others or the community. Call-in help lines, emotional assistance provided by others, and community support groups all represent social support systems where individuals can seek help and assistance from outside sources. On the other hand, the use of coping skills and verbalization for anger management refers to individual strategies rather than external social support.

2. When discussing the patterns of use of alcohol and other drugs, which piece of information should the nurse include?

• A. Lifetime prevalence and intensity of alcohol use are greater in men than in women.
• B. Caucasians report higher levels of alcohol use than African Americans or Hispanics.
• C. Overuse of alcohol and other drugs increases into the mid-20s, then levels off and decreases with age.
• D. Heavy use is more common in lower socioeconomic groups due to affordability.

Correct answer: C

Rationale: The correct answer is that overuse of alcohol and other drugs increases into the mid-20s, then levels off and decreases with age. Recent research indicates that alcohol and illicit drug use tends to rise into the mid-20s and then decline with age. Choices A and B are incorrect because lifetime prevalence and intensity of alcohol use are greater in men than in women, and Caucasians do not report higher levels of alcohol use compared to African Americans or Hispanics. Choice D is incorrect because heavy use is more common in lower socioeconomic groups due to factors like stress, coping mechanisms, and availability, not just affordability.

3. The client is receiving heparin for thrombophlebitis of the left lower extremity. Which of the following drugs reverses the effects of heparin?

• A. Cyanocobalamin
• B. Protamine sulfate
• C. Streptokinase
• D. Sodium warfarin

Correct answer: B

Rationale: The correct answer is Protamine sulfate. Protamine sulfate is the antidote for heparin, as it reverses its effects. Cyanocobalamin is a form of Vitamin B12 and is not used to reverse heparin effects. Streptokinase is a thrombolytic agent that is used to dissolve blood clots, not to reverse heparin effects. Sodium warfarin is an anticoagulant, but it is not the antidote for heparin. Therefore, answers A, C, and D are incorrect as they do not reverse the effects of heparin.

4. Which task should not be performed by the licensed practical nurse?

• A. Inserting a Foley catheter
• B. Discontinuing a nasogastric tube
• C. Obtaining a sputum specimen
• D. Initiating a blood transfusion

Correct answer: D

Rationale: A licensed practical nurse should not initiate a blood transfusion. LPNs can assist with transfusions and verify ID numbers but should not be assigned to initiate the procedure. Inserting Foley catheters, discontinuing nasogastric tubes, and obtaining sputum specimens are within the scope of practice for LPNs. Therefore, options A, B, and C are tasks that LPNs can perform, making them incorrect choices.

5. 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.
