Round off these numbers to the nearest tenth:
- A. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
- B. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
- C. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
- D. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
Correct Answer: B
Rationale: The correct answer is B. When rounding off to the nearest tenth, 1.027 becomes 1.0 because the digit in the hundredth's place is less than 5. For the other numbers, they are rounded correctly to the nearest tenth: 5.5778 = 5.6, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7. Therefore, option B is the most accurate in rounding off these numbers to the nearest tenth. Choices A, C, and D are incorrect as they do not round 1.027 to 1.0 as required when rounding to the nearest tenth.

Ben injects his insulin as prescribed, but then gets busy and forgets to eat. What will the best assessment of the nurse reveal?
- A. The client will be very thirsty.
- B. The client will complain of nausea.
- C. The client will need to urinate.
- D. The client will have moist skin.
Correct Answer: D
Rationale: The correct answer is D. In this scenario, since Ben took his insulin but forgot to eat, he is at risk of developing hypoglycemia. Moist skin is a sign of hypoglycemia, which can occur when blood sugar levels drop too low. Thirstiness (choice A) is more commonly associated with hyperglycemia (high blood sugar levels). Nausea (choice B) and frequent urination (choice C) are not typical immediate signs of hypoglycemia caused by missing a meal after insulin administration.
A charge nurse is making staff assignments on a medical-surgical unit. Which of the following tasks should the nurse plan to delegate to an assistive personnel?
- A. Measuring oxygen saturation for a client who has dyspnea
- B. Inserting a rectal suppository for a client who is vomiting
- C. Performing nasal hygiene for a client who has an NG tube
- D. Pouching a client's ostomy bag for a new colostomy
Correct Answer: D
Rationale: Pouching a new colostomy is a task that can be safely and appropriately delegated to an assistive personnel as it falls within their scope of practice. Measuring oxygen saturation (Choice A) requires a higher level of training and assessment, making it unsuitable for delegation. Inserting a rectal suppository (Choice B) and performing nasal hygiene (Choice C) involve invasive procedures that are typically performed by licensed nursing staff due to the associated risks and complexities, making them inappropriate for delegation to assistive personnel.
A case manager is preparing a discharge plan for a client following coronary artery bypass grafting surgery. Which of the following client issues should the nurse address first?
- A. Inadequate food supply
- B. Low pain tolerance
- C. Limited social support
- D. Decreased self-esteem
Correct Answer: A
Rationale: The nurse should address the inadequate food supply first as it directly impacts the client's health post-discharge. Proper nutrition is crucial for recovery after surgery, especially such as coronary artery bypass grafting. While low pain tolerance, limited social support, and decreased self-esteem are all important issues to address, addressing the client's nutritional needs is the priority in this scenario to ensure optimal recovery and healing.
Why is patient confidentiality significant in healthcare?
- A. Sharing patient information freely
- B. Protecting patient privacy
- C. Ignoring patient consent
- D. Limiting patient access to their own records
Correct Answer: B
Rationale: Patient confidentiality is significant in healthcare because it involves protecting patient privacy. Maintaining confidentiality ensures that patients feel safe and secure when sharing sensitive information with healthcare providers. Choice A is incorrect because sharing patient information freely would violate confidentiality. Choice C is incorrect because ignoring patient consent goes against ethical principles. Choice D is incorrect because limiting patient access to their own records does not relate directly to the concept of patient confidentiality.
Which of the following is the best argument for lower patient-to-nurse ratio?
- A. The more patients a nurse has, the better the nurse will be at catching early warning signs.
- B. Greater patient-to-nurse ratios decrease patient mortality.
- C. Adequate nurse levels do not impact the prevalence of urinary tract infections.
- D. Community nursing ratios do not impact Methicillin-resistant Staphylococcus aureus (MRSA) rates.
Correct Answer: B
Rationale: The best argument for lower patient-to-nurse ratios is that they decrease patient mortality. Choice A is incorrect because having more patients can lead to increased workload and decreased attention per patient. Choice C is incorrect as adequate nurse levels can indeed impact the prevalence of infections. Choice D is incorrect as community nursing ratios can impact MRSA rates due to potential transmission risks in healthcare settings.
