1. In the scientific method, a tentative solution to a problem is called a what?
- A. theory
- B. prediction
- C. hypothesis
- D. correlation
Correct answer: C
Rationale: In the scientific method, a hypothesis is a tentative solution or educated guess that is tested through research. A theory (choice A) is a well-substantiated explanation based on evidence and extensive testing. A prediction (choice B) is a statement about what will happen in the future based on existing knowledge. Correlation (choice D) refers to a mutual relationship between two or more things, indicating how they may change together but not providing a solution to a problem.
2. What does the term 'essential nutrient' refer to?
- A. A nutrient that can be synthesized by the body.
- B. A nutrient that is required for proper body functioning.
- C. A nutrient that must be obtained from the diet because the body cannot produce it.
- D. A nutrient that can be stored in the body for long periods.
Correct answer: C
Rationale: The correct answer is C. An essential nutrient is a substance that is necessary for normal body functioning but cannot be synthesized in adequate amounts by the body, therefore it must be obtained from the diet. Choices A, B, and D are incorrect because essential nutrients are not synthesized by the body, they are necessary for body functioning, and they are not typically stored in the body for long periods.
3. A nurse at a clinic is collecting data about pain from a client who reports severe abdominal pain. The nurse asks the client if there have been any accompanying nausea and vomiting. Which of the following pain characteristics is the nurse attempting to determine?
- A. Presence of associated manifestations.
- B. Location of the pain
- C. Pain quality
- D. Aggravating and relieving factors
Correct answer: A
Rationale: The nurse is identifying associated manifestations like nausea and vomiting that may occur with the pain. The presence of associated manifestations helps in understanding the broader clinical picture and potential causes of the pain. Location refers to where the pain is felt, pain quality describes the nature of the pain, and aggravating and relieving factors relate to what makes the pain worse or better. In this scenario, the focus is on identifying additional symptoms that can provide important diagnostic clues.
4. What is the first action a healthcare professional should take when a patient’s nasogastric (NG) tube becomes clogged?
- A. Flush the tube with water
- B. Reposition the patient
- C. Attempt to aspirate the clog with a syringe
- D. Administer a medication to dissolve the clog
Correct answer: C
Rationale: When a patient's nasogastric (NG) tube becomes clogged, the first action to take is to attempt to aspirate the clog with a syringe. This is a standard and initial step to clear the blockage in the tube. Flushing the tube with water (Choice A) may not address the specific clog; repositioning the patient (Choice B) is not directly related to clearing the tube. Administering a medication to dissolve the clog (Choice D) should only be considered after simpler methods like aspiration have been attempted.
5. What is the role of a nurse in patient education?
- A. Providing patients with necessary information to manage their health
- B. Limiting information to prevent confusion
- C. Using complex medical terminology
- D. Discouraging questions from patients
Correct answer: A
Rationale: The correct answer is A: Providing patients with necessary information to manage their health. Nurses play a crucial role in patient education by offering essential information to help patients understand and manage their health conditions. This empowers patients to make informed decisions about their health and improve their overall well-being. Choices B, C, and D are incorrect. Limiting information would hinder patient understanding and decision-making, using complex medical terminology can confuse patients, and discouraging questions goes against the essence of patient education.
