The body system that functions to maintain fluid balance, support immunity, and contains the spleen is the:
- A. Lymphatic System
- B. Digestive System
- C. Urinary System
- D. Respiratory System
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.

Which of the following questions is considered open-ended?
- A. What time did you last take your medications?
- B. Are you feeling okay right now?
- C. Please describe your symptoms.
- D. What day are you available for a follow-up appointment?
Correct Answer: C
Rationale: The correct answer is 'Please describe your symptoms.' This question is considered open-ended because it encourages the respondent to provide a detailed and descriptive answer, fostering a more elaborate response. Open-ended questions are designed to prompt thoughtful and detailed responses. Choice A is a closed-ended question since it seeks a specific time for the medication intake. Choice B is also closed-ended as it can be answered with a simple 'yes' or 'no,' limiting the response. Choice D is closed-ended as it requests a specific day for the follow-up appointment, restricting the range of possible responses.
Which complication of cardiac catheterization should the nurse monitor for in the initial 24 hours after the procedure?
- A. Angina at rest
- B. Thrombus formation
- C. Dizziness
- D. Falling blood pressure
Correct Answer: B
Rationale: Thrombus formation is a critical complication of cardiac catheterization that the nurse should monitor for in the initial 24 hours after the procedure. A thrombus can form in the blood vessels, obstructing blood flow and potentially leading to serious consequences such as embolism or organ ischemia. While angina at rest, dizziness, and falling blood pressure are potential complications following cardiac catheterization, they are not typically associated with the immediate post-procedural period. Monitoring for thrombus formation is essential to ensure early detection and intervention, which can prevent serious complications.
You have been assigned to take an apical pulse for one of the patients on the nursing unit. How will you do this?
- A. You will place the stethoscope over the heart and listen for any irregular beats.
- B. You will place the stethoscope over the heart and count the beats per minute.
- C. You will place your fingertip over the patient's wrist and feel for any irregular beats.
- D. You will place your fingertip over the patient's wrist and count the beats per minute.
Correct Answer: B
Rationale: To take an apical pulse accurately, you should place the stethoscope over the heart and count the number of beats per minute. This method provides a precise assessment of the heart rate. While listening for irregular beats is essential for assessing the heart's rhythm, the primary objective of taking an apical pulse is to determine the heart rate. Choices C and D are incorrect because the apical pulse is not taken at the wrist; instead, it is obtained by auscultating at the apex of the heart, usually at the point where the fifth intercostal space meets the midclavicular line.
A patient suffering from hyperglycemia would be experiencing:
- A. Low blood sugar
- B. High blood sugar
- C. Normal blood sugar
- D. None of the above
Correct Answer: B
Rationale: Hyperglycemia is a condition characterized by high blood sugar levels. In this state, there is an excess of glucose in the bloodstream. Patients with hyperglycemia are often diagnosed with diabetes. The term 'hyperglycemia' specifically refers to elevated blood sugar levels. Therefore, the correct answer is 'High blood sugar.' Choices A, C, and D are incorrect because hyperglycemia indicates elevated blood sugar levels and not low or normal levels.
A patient who is displaying the defense mechanism of Compensation would:
- A. Refuse to hear unwanted information.
- B. Transfer feelings of negativity to someone else.
- C. Overemphasize behaviors which accommodate for perceived weaknesses.
- D. Place blame on others for personal actions or mistakes.
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.
