1. Which of the following proteins is iron a component of, responsible for the transport of oxygen in the bloodstream?
- A. hemoglobin
- B. transferrin
- C. myoglobin
- D. hepcidin
Correct answer: A
Rationale: The correct answer is A: hemoglobin. Hemoglobin is the protein found in red blood cells that is responsible for carrying oxygen from the lungs to the rest of the body. Iron is a crucial component of hemoglobin, binding to oxygen and allowing for its transport. Choice B, transferrin, is involved in iron transport in the blood but not in oxygen transport. Choice C, myoglobin, is a protein found in muscle cells that stores oxygen for muscle use, not transportation in the bloodstream. Choice D, hepcidin, is a peptide hormone that regulates iron absorption in the intestines and iron distribution in the body, but it is not directly involved in oxygen transport.
2. High blood pressure is defined as systolic and diastolic measurements greater than or equal to:
- A. 140 mm Hg and 90 mm Hg, respectively
- B. 150 mm Hg and 80 mm Hg, respectively
- C. 160 mm Hg and 110 mm Hg, respectively
- D. 180 mm Hg and 120 mm Hg, respectively
Correct answer: A
Rationale: High blood pressure, or hypertension, is typically defined as having a systolic pressure of 140 mm Hg or higher and/or a diastolic pressure of 90 mm Hg or higher. Therefore, the correct answer is A. Choice B is incorrect because it suggests a higher systolic measurement than the standard definition. Choice C is incorrect as it provides an even higher systolic measurement and a much higher diastolic measurement. Choice D is also incorrect as it suggests extremely elevated blood pressure values, well above the typical definition of hypertension.
3. In preparation for ECT, the nurse knows that it is almost similar to that of:
- A. ECG
- B. General Anesthesia
- C. EEG
- D. MRI
Correct answer: B
Rationale: The correct answer is B: General Anesthesia. In preparation for ECT (Electroconvulsive Therapy), the nurse should be aware that it is almost similar to the process of administering general anesthesia. This similarity is crucial as it involves sedation and muscle relaxation to ensure safety during the procedure. Choice A (ECG) is incorrect because ECT and ECG (Electrocardiogram) serve different purposes and involve distinct procedures. Choice C (EEG) is incorrect as EEG (Electroencephalogram) measures brain activity and is not directly related to ECT. Choice D (MRI) is also incorrect as MRI (Magnetic Resonance Imaging) is a diagnostic imaging procedure that does not involve sedation or muscle relaxation like ECT and general anesthesia.
4. Based on the Code of Ethics for Filipino Nurses, what is regarded as the hallmark of nursing responsibility and accountability?
- A. Human rights of clients, regardless of creed and gender
- B. The privilege of being a registered professional nurses
- C. Health, being a fundamental right of every individual
- D. Accurate documentation of actions and outcomes
Correct answer: B
Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
5. Proteolytic enzymes are most likely to break down which food type?
- A. Carbohydrates
- B. Proteins
- C. Fats
- D. Lipids
Correct answer: B
Rationale: Proteolytic enzymes target proteins for breakdown into amino acids. Carbohydrates are broken down by enzymes like amylase, while fats are broken down by lipase. Lipids, which include fats, are not specifically targeted by proteolytic enzymes.
