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.

Marlisa has been diagnosed with diabetes mellitus type 1. She asks Nurse Errol what this means. What is the best response by the nurse? Select the one that does not apply.
- A. Your beta cells should be able to secrete insulin, but cannot.
- B. The endocrine function of your pancreas is to secrete insulin.
- C. Without insulin, you will develop ketoacidosis (DKA).
- D. The exocrine function of your pancreas is to secrete Estrogen.
Correct Answer: D
Rationale: Type 1 diabetes is characterized by the inability of the beta cells in the pancreas to secrete insulin. Choice A is correct because it highlights the role of beta cells. Choice B is accurate as the endocrine function of the pancreas includes insulin secretion. Choice C is true as without insulin, ketoacidosis can develop. Choice D is incorrect as the exocrine function of the pancreas involves secreting digestive enzymes, not estrogen.
What is idiopathic thrombocytopenia purpura?
- A. Highly similar to disseminated intravascular coagulation (DIC).
- B. Caused by the overproduction of platelets.
- C. A bleeding disorder that is characterized by too few platelets.
- D. Treated with immune system-boosting medications.
Correct Answer: C
Rationale: Idiopathic thrombocytopenic purpura is a bleeding disorder characterized by a low number of platelets in the blood. This condition is not highly similar to disseminated intravascular coagulation (DIC), which involves abnormal clotting throughout the body (coagulation), leading to depletion of platelets. Choice B is incorrect because idiopathic thrombocytopenic purpura is actually characterized by a decrease in platelet count, not an overproduction. While immune system-boosting medications may be used in some cases, the primary treatment for idiopathic thrombocytopenic purpura focuses on increasing platelet counts or managing symptoms.
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.
Select the criteria that is accurately paired with its indication of birth weight or gestational age.
- A. Low birth weight: The neonate's weight is less than 1,500 g at the time of delivery.
- B. Appropriate for gestational age: The neonate's weight ranges from the 10th to the 90th percentile.
- C. Large for gestational age: The neonate's weight is above the 99th percentile.
- D. Small for gestational age: The neonate's weight is below the 20th percentile.
Correct Answer: B
Rationale: Appropriate for gestational age (AGA) indicates a neonate's weight ranging from the 10th to the 90th percentile. This range signifies that the baby's weight is within the normal range for their gestational age. Choices A, C, and D provide inaccurate information about the criteria and do not correctly correspond to the indicated birth weight or gestational age. Low birth weight typically refers to a weight below 2,500 g, large for gestational age above the 90th percentile, and small for gestational age below the 10th percentile.
To resolve a conflict between staff members regarding potential changes in policy, a nurse manager decides to implement the changes she prefers regardless of the feelings of those who oppose those changes. Which of the following conflict-resolution strategies is the nurse manager using?
- A. Competing
- B. Collaborating
- C. Compromising
- D. Cooperating
Correct Answer: A
Rationale: The nurse manager is utilizing the competing conflict-resolution strategy. Competing involves making decisions based on one's preferences without considering the opinions or feelings of others. In this scenario, the nurse manager is unilaterally implementing changes despite opposition, demonstrating a competitive approach. Collaborating involves working together to find a mutually beneficial solution, compromising involves finding a middle ground acceptable to both parties, and cooperating involves working together towards a shared goal. These options are not applicable in this situation as the nurse manager is imposing her preferred changes without regard for others' input.
