Nursing Elites

1. Which enzyme is most essential for hydrolyzing large protein molecules?

• A. Gastric lipase
• B. Pepsin
• C. Mucus
• D. Intrinsic factor

Correct answer: B

Rationale: Pepsin, choice B, is the correct answer as it is a proteolytic enzyme that is essential for the breakdown of large protein molecules in the stomach. Gastric lipase, choice A, is incorrect because it primarily targets fats, not proteins, hence it is not involved in protein hydrolysis. Mucus, choice C, is incorrect as it serves to protect the stomach lining from acidic gastric juices and does not play a direct role in protein digestion. Intrinsic factor, choice D, is incorrect as it is vital for the absorption of Vitamin B12 in the small intestine and doesn't participate in the process of hydrolyzing proteins.

2. Low levels of high-density lipoproteins (HDL) are?

• A. associated with being underweight
• B. more prevalent in males
• C. highly predictive of CHD risk
• D. not a good predictor of CHD risk

Correct answer: C

Rationale: Low levels of HDL cholesterol are a strong predictor of coronary heart disease (CHD) risk because HDL helps to remove excess cholesterol from the bloodstream. Choice A is incorrect because low HDL levels are not associated with being underweight but rather with increased CHD risk. Choice B is incorrect as low HDL levels are not more prevalent in males but can affect both genders. Choice D is incorrect as low levels of HDL are indeed a good predictor of CHD risk.

3. This vaccine content is derived from RNA recombinants.

• A. Measles C. Hepatitis B vaccines
• B. Tetanus toxoids D. DPT
• C.
• D.

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

4. What is the term for a state of disequilibrium wherein a person cannot readily solve a problem or situation using their usual coping mechanisms?

• A. Crisis
• B. Mental health
• C. Mental illness
• D. Stress

Correct answer: A

Rationale: In psychological terms, a 'Crisis' refers to a state of disequilibrium wherein a person cannot readily solve a problem or situation even by using his usual coping mechanisms. This is different from 'Mental Illness' (Choice C) which is a more general term for a wide range of mental health conditions that affect mood, thinking and behavior. 'Mental Health' (Choice B) is a state of well-being in which an individual realizes his or her own abilities, can cope with the normal stresses of life, can work productively and is able to make a contribution to his or her community. Finally, 'Stress' (Choice D) is a state of mental or emotional strain or tension resulting from adverse or demanding circumstances, but it does not necessarily disrupt equilibrium to the extent that usual coping mechanisms are ineffective, unlike 'Crisis'.

5. While on Bryant’s traction, which of these observations of Graciela and her traction apparatus would indicate a decrease in the effectiveness of her traction?

• A. Graciela’s buttocks are resting on the bed.
• B. The traction weights are hanging 10 inches above the floor.
• C. Graciela’s legs are suspended at a 90 degree angle to her trunk.
• D. The traction ropes move freely through the pulley.

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
