1. . Edema, characterized by swelling due to fluid buildup, can be a sign of:

• A. Heart failure
• B. Liver disease
• C. Lymphatic system dysfunction
• D. All of the above

Correct answer: D

Rationale: Edema, which is the accumulation of fluid in tissues leading to swelling, can be caused by various medical conditions. Heart failure can result in fluid retention due to the heart's inability to pump effectively, leading to edema. Liver disease can cause edema by impairing the liver's ability to produce proteins that help maintain fluid balance. Dysfunction of the lymphatic system can also lead to edema, as the lymphatic vessels play a crucial role in draining excess fluid from tissues. Therefore, all the options (heart failure, liver disease, and lymphatic system dysfunction) can contribute to the development of edema, making 'All of the above' the correct answer.

2. Which of the following is NOT a symptom of asthma, a chronic respiratory condition?

• A. Wheezing
• B. Difficulty breathing
• C. Chest tightness
• D. Fever

Correct answer: D

Rationale: The correct answer is D: "Fever." Fever is not a symptom commonly associated with asthma. Asthma symptoms typically include wheezing (A), difficulty breathing (B), and chest tightness (C). Wheezing is a high-pitched whistling sound that occurs during breathing, while difficulty breathing refers to the feeling of not getting enough air. Chest tightness is a common sensation of pressure or constriction in the chest. Fever is not a typical symptom of asthma but may occur in other respiratory conditions or infections. Therefore, fever is the correct answer as it does not align with the typical symptom profile of asthma.

3. The electrical conductivity of a strong acid solution is higher than that of a weak acid solution because:

• A. Strong acids are more concentrated.
• B. Strong acids release more hydrogen ions
• C. Weak acids are better at dissolving salts.
• D. Strong acids have a lower pH.

Correct answer: B

Rationale: Strong acids completely dissociate, leading to a h

4. What is the law of conservation of energy?

• A. Energy cannot be created, only destroyed
• B. Energy can be created but not destroyed
• C. Energy can neither be created nor destroyed, only transformed from one form to another
• D. Energy is always created in any process

Correct answer:

Rationale: According to the law of conservation of energy, the total energy in a closed system remains constant; it can change forms but cannot be created or destroyed.

5. Which neurotransmitter is associated with mood regulation, sleep, and appetite?

• A. Acetylcholine
• B. Dopamine
• C. Serotonin
• D. GABA (Gamma-aminobutyric acid)

Correct answer: c

Rationale: The correct answer is C: Serotonin. Serotonin is a neurotransmitter that plays a crucial role in mood regulation, sleep, and appetite. It is often referred to as the 'feel-good' neurotransmitter because it helps regulate mood and emotional well-being. Serotonin is also involved in controlling sleep patterns and appetite, making it essential for maintaining a healthy balance in these areas. Acetylcholine is mainly associated with muscle movement and memory, while dopamine is linked to pleasure and reward pathways. GABA is an inhibitory neurotransmitter that helps reduce neuronal excitability. Therefore, serotonin is the neurotransmitter most closely associated with mood regulation, sleep, and appetite.

6. One staff suggests that they review the pattern of nursing care that they are using, which is

• A. job description
• B. system used to deliver care
• C. manual of procedure
• D. rules to be followed

Correct answer: B

Rationale: The correct answer is B: 'system used to deliver care.' When a staff member suggests reviewing the pattern of nursing care being used, they are referring to the overall system or method in place for delivering care to patients. This includes the processes, protocols, and techniques used to provide nursing care. It goes beyond just following a job description, manual of procedure, or rules. By evaluating and potentially revising the system used to deliver care, staff can ensure that best practices are in place to provide high-quality and effective care to patients.
