Correct Answer: C

Rationale: The correct answer is counting the pulse for 15 seconds and multiplying the number by four.
To accurately assess a patient's heart rate or pulse, it is crucial to count the pulse for a full minute. Counting for only 15 seconds and then multiplying by four may result in an inaccurate heart rate calculation. This approach could miss arrhythmias or intermittent pulsations that could be vital indicators of the patient's condition. Placing the index finger on the radial artery, which is located on the thumb side of the patient's wrist, is the correct technique for taking a pulse. Noting a pulse as 'weak' when the pulsation disappears upon adding pressure is a valid observation and not an error in itself.
Therefore, the most common error in this scenario is incorrectly calculating the pulse rate by multiplying a 15-second count by four.

Correct Answer: A

Rationale: The correct answer is that the pulse rate starts out fast and decreases as the patient ages. In infants, the normal pulse rate is around 140 beats per minute, which then falls to an average of 80 beats per minute in adults. As individuals age, their pulse rate tends to decrease due to changes in cardiovascular function.
Choice B is incorrect as the pulse rate typically decreases with age, rather than increases.
Choice C is incorrect as there is a general trend of decreasing pulse rate as individuals age, rather than a continuous variation.
Choice D is incorrect as the pulse rate does change over a patient's lifespan, starting fast in infants and decreasing as they age.

Correct Answer: D

Rationale: The highest priority nursing intervention in this scenario should be suicide precautions. The patient's statement indicates suicidal ideation, which poses an immediate risk to their safety. By implementing suicide precautions, the nurse can ensure constant monitoring and intervention to prevent any self-harm. While addressing self-esteem, anxiety, and sleep issues are essential, ensuring the patient's safety by prioritizing suicide precautions is crucial. Self-esteem-building activities, anxiety self-control measures, and sleep enhancement activities are important interventions but should follow the immediate concern of preventing harm from suicidal thoughts.

Correct Answer: C

Rationale: The correct answer is 'Overemphasize behaviors which accommodate for perceived weaknesses.' Compensation involves overemphasizing or exaggerating a particular behavior or trait to make up for or cover up perceived weaknesses in oneself. This defense mechanism allows individuals to focus on their strengths rather than acknowledging their shortcomings.

Choices A, B, and D are incorrect. Refusing to hear unwanted information relates more to denial, transferring feelings of negativity to someone else is projection, and placing blame on others is an example of the defense mechanism known as externalization.

Correct Answer: A

Rationale: The Lymphatic System is responsible for maintaining fluid balance and supporting immunity. It contains organs like the spleen, tonsils, thymus, lymph nodes, and lymph vessels. The spleen, a part of the lymphatic system, plays a crucial role in filtering blood and storing blood cells. The Digestive System is primarily involved in the breakdown and absorption of nutrients, not fluid balance or immunity. The Urinary System is responsible for filtering waste products from the blood and regulating fluid balance, but it does not support immunity or contain the spleen. The Respiratory System is focused on gas exchange and oxygenating the blood, not fluid balance or immunity.
