Adult Health 1 Final Exam
1. When taking blood pressure at the brachial artery, the nurse should place the client's arm in which position?
- A. Slightly above the level of the heart
- B. At the level of the heart
- C. At a level of comfort for the client
- D. Below the level of the heart
Correct answer: B
Rationale: When taking blood pressure at the brachial artery, it is crucial to place the client's arm at the level of the heart to ensure accurate measurement. Placing the arm above or below the heart level can lead to incorrect readings. Option A, placing the arm slightly above the heart level, would result in falsely lower blood pressure readings as gravity would assist in a lower value. Option C, placing the arm at a level of comfort for the client, may not align with the standardized technique required for accurate blood pressure assessment. Option D, placing the arm below the level of the heart, would likely yield falsely higher blood pressure readings due to increased hydrostatic pressure pushing the blood against gravity.
2. When orienting a newly licensed nurse on taking a telephone prescription, which statement indicates understanding of the process?
- A. A second nurse enters the prescription into the client’s medical record.
- B. Another nurse should listen to the phone call.
- C. The provider can clarify the prescription when they sign the health record.
- D. I should omit the 'read back' if this is a one-time prescription.
Correct answer: A
Rationale: The correct answer is A because a second nurse should verify and enter the prescription into the client’s medical record to ensure accuracy. This step is crucial to prevent errors in transcription and administration. Choice B is incorrect as having another nurse listen to the phone call does not ensure accurate transcription. Choice C is incorrect because the provider clarifying the prescription upon signing the health record does not replace the need for proper documentation. Choice D is incorrect because the 'read back' process is essential for all telephone prescriptions to confirm accuracy and prevent errors in transcription or administration.
3. Which of the following conditions is considered a multifactorial problem?
- A. Cystic fibrosis
- B. Down syndrome
- C. Diabetes mellitus
- D. XYY syndrome
Correct answer: C
Rationale: The correct answer is 'Diabetes mellitus' because it is a multifactorial disease, influenced by both genetic predisposition and environmental factors. Cystic fibrosis (choice A) is primarily a genetic disorder caused by mutations in the CFTR gene. Down syndrome (choice B) is due to an extra copy of chromosome 21. XYY syndrome (choice D) is a genetic condition where males have an extra Y chromosome. These conditions are not considered multifactorial as their origins are primarily genetic.
4. At what age does a 9-year-old child typically lose which of the following teeth?
- A. Central incisor
- B. Second molar
- C. Lateral incisor
- D. Cuspid
Correct answer: A
Rationale: A 9-year-old child typically loses their central incisors, not the lateral incisors or second molars. The central incisors are usually among the first teeth that children lose around 6 to 7 years of age, as part of the natural process of shedding primary teeth to make way for permanent teeth. The second molars and cuspids are typically lost later in the mixed dentition phase. Therefore, option A, 'Central incisor,' is the correct answer.
5. When using an open irrigation technique to irrigate a client's indwelling urinary catheter, which of the following actions should the nurse take?
- A. Place the client in a side-lying position
- B. Instill 15 mL of irrigation fluid into the catheter with each flush
- C. Subtract the amount of irrigant used from the client's urine output
- D. Perform the irrigation using a 20 mL syringe
Correct answer: C
Rationale: The correct action for the nurse to take when using an open irrigation technique on a client with an indwelling urinary catheter is to subtract the amount of irrigant used from the client's urine output. This calculation helps ensure an accurate measurement of the client's actual urine output by accounting for the irrigation fluid introduced into the catheter. Placing the client in a side-lying position (Choice A) is not directly related to the irrigation procedure. Instilling a specific volume of irrigation fluid (Choice B) may vary depending on the client's condition and the healthcare provider's order. Using a 20 mL syringe for irrigation (Choice D) is a matter of equipment choice and does not directly impact the calculation of urine output in this context.
