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.

Which nursing diagnosis is commonly used among patients affected by fibromyalgia?
- A. Decreased self-care in activities of daily living related to fatigue
- B. Impaired mental functioning related to electrolyte imbalances
- C. Increased vigilance secondary to electrolyte imbalances
- D. At risk for a swallowing disorder related to fibromyalgia
Correct Answer: A
Rationale: The correct answer is A: 'Decreased self-care in activities of daily living related to fatigue.' Patients with fibromyalgia commonly experience fatigue, which can lead to decreased ability to perform self-care activities. This nursing diagnosis addresses a direct consequence of fibromyalgia. Choices B, C, and D are incorrect because they do not directly correlate with the common manifestations of fibromyalgia. Impaired mental functioning related to electrolyte imbalances and increased vigilance secondary to electrolyte imbalances are not typical presentations of fibromyalgia. 'At risk for a swallowing disorder related to fibromyalgia' is not a common nursing diagnosis associated with fibromyalgia; swallowing disorders are not a primary symptom of this condition.
Low birth weight is defined as a newborn's weight of:
- A. 2500 grams or less at birth, regardless of gestational age.
- B. 1500 grams or less at birth, regardless of gestational age.
- C. 2500 grams or less at birth, according to gestational age.
- D. 1500 grams or less at birth, according to gestational age.
Correct Answer: A
Rationale: Low birth weight is defined as 2500 grams or less at birth, regardless of gestational age. This means that any newborn weighing 2500 grams or less is considered to have a low birth weight, irrespective of how many weeks they were in the womb. Choices B, C, and D are incorrect because they specify a weight of 1500 grams or less, which is not the standard definition of low birth weight. The correct definition is 2500 grams or less, not influenced by gestational age.
A nurse in the emergency department is performing triage for a group of clients who were in a train crash. Which of the following clients should the nurse tag as emergent?
- A. A client who has an open fracture of the femur
- B. A client who has periorbital ecchymosis
- C. A client who has asymmetrical thorax
- D. A client who has a deep-partial thickness burn on the lower extremities
Correct Answer: C
Rationale: In a triage situation, an asymmetrical thorax suggests a potentially life-threatening condition such as a pneumothorax or hemothorax, requiring immediate attention. This client should be tagged as emergent. Periorbital ecchymosis and deep-partial thickness burns, while concerning, may not indicate an immediate life-threatening situation. An open fracture of the femur, although serious, can be prioritized after addressing emergent cases.
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 manifestation should the nurse expect to assess in a patient with fluid volume deficit?
- A. Headache and muscle cramps
- B. Dyspnea and respiratory crackles
- C. Increased pulse rate and blood pressure
- D. Orthostatic hypotension and flat neck veins
Correct Answer: D
Rationale: Orthostatic hypotension and flat neck veins are classic manifestations of fluid volume deficit. When the body loses fluid, blood volume decreases, leading to decreased venous return to the heart, resulting in orthostatic hypotension and flat neck veins. Choices A, B, and C are more indicative of other conditions such as dehydration, respiratory issues, or compensatory mechanisms in response to hypovolemia, respectively.
