What is the mineral necessary for chemical clotting?
- A. Iron
- B. Potassium
- C. Sodium
- D. Calcium
Correct Answer: D
Rationale: The correct answer is D: Calcium. Calcium is necessary for the chemical clotting process because it plays a crucial role in the activation of various clotting factors, leading to the formation of a blood clot. Without sufficient calcium, the clotting cascade would not be able to proceed effectively. Iron (choice A) is essential for red blood cell production, not clotting. Potassium (choice B) and Sodium (choice C) are important for various physiological functions but are not directly involved in the clotting process.

A nurse changes a client’s wound dressing according to the protocol outlined by the health care agency. What type of nursing intervention is this?
- A. Independent intervention
- B. Dependent intervention
- C. Interdependent intervention
- D. Collaborative intervention
Correct Answer: C
Rationale: The correct answer is C: Interdependent intervention. This type of nursing intervention involves collaboration with other healthcare professionals to provide holistic care. In this scenario, the nurse is following a protocol set by the health care agency, which likely involves input and guidance from various team members. The nurse's actions require coordination and communication with others to ensure the best outcome for the client.
Choice A (Independent intervention) would involve actions that the nurse can perform autonomously without requiring direction from others. Choice B (Dependent intervention) would require an order or prescription from a healthcare provider for the nurse to carry out. Choice D (Collaborative intervention) involves working together with other healthcare professionals on a specific aspect of care, but in this case, the nurse is primarily following a set protocol without necessarily actively collaborating with others during the task.
For a patient who is being discharged on digoxin, the nurse should include which of the ff. in an explanation to the patient on the signs and symptoms of digoxin toxicity?
- A. Poor appetite
- B. Halos around lights
- C. Constipation
- D. Tachycardia
Correct Answer: B
Rationale: The correct answer is B: Halos around lights. Digoxin toxicity can cause visual disturbances like seeing halos around lights, which is a common symptom. This is due to its effect on the eyes. Poor appetite (choice A) is a common side effect but not specific to toxicity. Constipation (choice C) is not a typical sign of digoxin toxicity. Tachycardia (choice D) is more commonly associated with digoxin toxicity, but visual disturbances like halos around lights are more specific and should be explained to the patient.
Which of the following is an adverse reaction to glipizide (Glucotrol)?
- A. Headache
- B. Hypotension
- C. Constipation
- D. Photosensitivity
Correct Answer: B
Rationale: The correct answer is B: Hypotension. Glipizide is a sulfonylurea medication used to treat diabetes by lowering blood sugar levels. Hypotension, or low blood pressure, can be an adverse reaction as glipizide may cause vasodilation leading to a drop in blood pressure. Headache (choice A), constipation (choice C), and photosensitivity (choice D) are not common adverse reactions associated with glipizide use. Headache may occur due to other factors, constipation is more commonly associated with opioids, and photosensitivity is typically seen with certain antibiotics or NSAIDs.
The nursing diagnosis Impaired Gas Exchange, prioritized by Maslow’s hierarchy of basic human needs, is appropriate for what level of needs?
- A. Physiologic
- B. Safety
- C. Love and belonging
- D. Self-actualization
Correct Answer: A
Rationale: The correct answer is A: Physiologic. Impaired Gas Exchange pertains to the basic physiological need for oxygenation, which is fundamental for survival. Maslow's hierarchy states that physiological needs are the most fundamental and must be met before progressing to higher-level needs. Safety, love and belonging, and self-actualization are higher-level needs compared to physiological needs. Therefore, Impaired Gas Exchange aligns with the physiological level of needs in Maslow's hierarchy.
While interviewing an older female patient of Asian descent, the nurse notices that the patient looks at the ground when answering questions. What should the nurse do?
- A. Consider cultural differences during this assessment.
- B. Ask the patient to make eye contact to determine her affect.
- C. Continue with the interview and document that the patient is depressed.
- D. Notify the health care provider to recommend a psychological evaluation.
Correct Answer: A
Rationale: The correct answer is A: Consider cultural differences during this assessment. In many Asian cultures, avoiding direct eye contact is a sign of respect rather than depression. The nurse should be culturally sensitive and understand that different cultures have varying communication norms. By considering cultural differences, the nurse can build rapport and trust with the patient. Asking the patient to make eye contact (B) may be perceived as disrespectful and may hinder effective communication. Continuing with the interview and assuming depression (C) without further assessment is premature and may lead to misdiagnosis. Notifying the health care provider for a psychological evaluation (D) is not necessary at this stage as the behavior observed may be culturally influenced.
