1. What is the absorbable unit of a protein?
- A. Amino acid
- B. Pepsin
- C. Glucose
- D. Sucrose
Correct answer: A
Rationale: Amino acids are the correct answer because they are the building blocks of proteins that the body absorbs after digestion. Pepsin, choice B, is incorrect as it is an enzyme that aids in the digestion of proteins, not the absorbable unit of them. Choices C and D, glucose and sucrose, are wrong because they are types of sugars, not proteins.
2. A nurse is caring for four hospitalized clients. Which of the following clients should the nurse identify as being at risk for fluid volume deficit?
- A. The client who has been NPO since midnight for endoscopy
- B. The client who has left-sided heart failure and has a brain natriuretic peptide (BNP) level of 600 pg/mL
- C. The client who has end-stage renal failure and is scheduled for dialysis today
- D. The client who has gastroenteritis and is febrile
Correct answer: The client who has gastroenteritis and is febrile
Rationale: Gastroenteritis can lead to fluid loss through vomiting and diarrhea, especially when accompanied by fever. Fever can increase insensible water loss through sweating as well. Both vomiting and diarrhea can significantly contribute to fluid volume deficit, making the client with gastroenteritis and fever at higher risk compared to the other clients described in the options.
3. What ECG changes are seen with hyperkalemia?
- A. Flattened T waves
- B. Elevated ST segments
- C. Prominent U waves
- D. Widened QRS complex
Correct answer: A
Rationale: Flattened T waves are an early ECG sign of hyperkalemia. Hyperkalemia affects the repolarization phase of the cardiac action potential, leading to changes such as peaked T waves, prolonged PR interval, widened QRS complex, and ultimately sine wave pattern. Elevated ST segments, prominent U waves, and widened QRS complex are not typically associated with hyperkalemia, making choices B, C, and D incorrect.
4. A resident on night call refuses to answer pages from the staff nurse on the night shift and complains that she calls too often with minor problems. The nurse feels offended and reacts with frequent, middle-of-the-night phone calls to 'get back' at him. The behavior displayed by the resident and the nurse is an example of what kind of conflict?
- A. Perceived conflict
- B. Disruptive conflict
- C. Competitive conflict
- D. Felt conflict
Correct answer: B
Rationale: The behavior displayed by the resident and the nurse is an example of disruptive conflict. In disruptive conflict, the parties involved engage in activities to reduce, defeat, or eliminate the opponent. The resident refusing to answer calls and the nurse retaliating with frequent calls to 'get back' at him exemplify behaviors aimed at causing disruption and conflict between them. Perceived conflict refers to each party's perception of the other's position, competitive conflict involves one side winning at the expense of the other, and felt conflict is about the feelings of opposition within the relationship, none of which fully capture the nature of the conflict displayed in this scenario.

On assessment, you find the patient tachypnic, lethargic, weak, and exhibiting a diminished cognitive ability. You also find 3+ pitting edema. What electrolyte imbalance is the most plausible cause of this patients signs and symptoms?
- A. Hypocalcemia
- B. Hyponatremia
- C. Hyperchloremia
- D. Hypophosphatemia
Correct answer: Hyperchloremia
Rationale:
