Nursing Elites

1. Fat emulsions are frequently administered as a part of total parenteral nutrition. Which statement is true regarding fat emulsions?

• A. They have a high energy-to-fluid-volume ratio.
• B. Even though hypertonic, they are well tolerated.
• C. They are a basic solution due to the addition of sodium hydroxide (NaOH).
• D. The pH is alkaline, making them compatible with most medications.

Correct answer: A

Rationale: The correct statement is that fat emulsions have a high energy-to-fluid-volume ratio. Fat emulsions are formulated in 10%, 20%, and 30% solutions and supply 1.1, 2, and 3 kilocalories, respectively, for each milliliter. In comparison, a milliliter of 5% dextrose only supplies 0.17 kilocalories. Choices B, C, and D are incorrect. Choice B is false because fat emulsions are essentially pH neutral and isotonic, not hypertonic. Choice C is incorrect because fat emulsions are not basic solutions; they are essentially pH neutral. Choice D is incorrect as fat emulsions are not alkaline; they are pH neutral, making them compatible with most medications.

2. The client is taking prednisone 7.5mg po each morning to treat his systemic lupus erythematosus. Which statement best explains the reason for taking the prednisone in the morning?

• A. There is less chance of forgetting the medication if taken in the morning.
• B. There will be less fluid retention if taken in the morning.
• C. Prednisone is absorbed best with the breakfast meal.
• D. Morning administration mimics the body's natural secretion of corticosteroid.

Correct answer: D

Rationale: Taking corticosteroids in the morning mimics the body's natural release of cortisol, which follows a diurnal pattern with higher levels in the morning. This timing helps regulate the body's inflammatory response and minimizes potential side effects. Answer A is not the primary reason for morning dosing, as adherence concerns can be addressed through other means. Answer B is incorrect since fluid retention is not influenced by the timing of prednisone administration. Answer C is also incorrect as prednisone absorption is not significantly affected by whether it is taken with breakfast or not.

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. Who may legally give informed consent?

• A. an 86-year-old male with advanced Alzheimer's disease
• B. a 14-year-old girl needing an appendectomy who is not an emancipated minor
• C. a 14-year-old girl needing an appendectomy who is not an emancipated minor
• D. a 6-month-old baby needing bowel surgery

Correct answer: C

Rationale: The correct answer is a 14-year-old girl needing an appendectomy who is not an emancipated minor. Informed consent can be given by individuals who are competent and not minors. Minors are generally unable to provide informed consent unless they are emancipated. Choice A is incorrect because an 86-year-old male with advanced Alzheimer's disease is considered incompetent to make decisions. Choice D is incorrect because a 6-month-old baby is unable to provide consent. Emancipated minors are an exception to the minor rule, as they can provide consent for their own treatment.

5. A client goes to the mental health center for difficulty concentrating, insomnia, and nightmares. The client reports being raped as a child. The nurse should assess the client for further signs of:

• A. generalized anxiety disorder.
• B. schizophrenia.
• C. post-traumatic stress disorder.
• D. bipolar disorder.

Correct answer: C

Rationale: Given the history of childhood sexual abuse and the presenting symptoms of difficulty concentrating, insomnia, and nightmares, the nurse should assess the client for post-traumatic stress disorder (PTSD). Childhood sexual abuse is strongly associated with adult-onset depression and an increased risk for PTSD. Individuals with PTSD may exhibit re-experiencing symptoms such as flashbacks, nightmares, and heightened reactions to trauma triggers. They may also display emotional numbing, avoidance behaviors, and increased arousal symptoms like difficulty sleeping and hypervigilance. Generalized anxiety disorder (Choice A) is characterized by excessive worry and anxiety about various events or activities, not necessarily tied to a specific trauma. Schizophrenia (Choice B) is a severe mental disorder characterized by distortions in thinking, perception, emotions, and behavior, unrelated to the traumatic event described. Bipolar disorder (Choice D) involves mood swings between depressive and manic episodes, and its symptoms differ from those typically seen in PTSD.
