Select all of the risk factors that are associated with deep vein thrombosis.

Correct Answer: A

Rationale: The correct answer is A: "The use of oral contraceptives." Risk factors for deep vein thrombosis include factors such as immobility, surgery, cancer, obesity, smoking, and the use of oral contraceptives. Choices B, C, and D are incorrect because blood type and Rh factor do not play a role in the development of deep vein thrombosis, and being underweight is not typically considered a risk factor for this condition.

Correct Answer: B

Rationale: The correct answer is Stage II. During Stage II of anesthesia, a patient is most likely to experience involuntary motor activity. This stage is known as the excitement stage, where the patient may exhibit purposeful or involuntary movements. Choice A (Stage I) is incorrect because Stage I is the induction phase where the patient is transitioning from consciousness to unconsciousness, and involuntary motor activity is less likely to occur. Choice C (Stage III) is incorrect as it is the stage of surgical anesthesia characterized by muscle relaxation, and involuntary motor activity is less common during this stage. Choice D (Stage VI) is incorrect as there is no Stage VI in the standard stages of anesthesia. Therefore, the most appropriate stage where involuntary motor activity is likely to occur is Stage II.

Correct Answer: D

Rationale: Using clean gloves rather than sterile gloves for colostomy care is a cost-effective measure without compromising care quality. This choice helps in reducing costs without compromising patient safety. Storing opened bottles of normal saline in a refrigerator for up to 48 hours (Choice A) may lead to contamination risks. Returning unused supplies to the unit's supply stock (Choice B) can be inefficient and lead to potential waste. Waiting to dispose of sharps containers until they are completely full (Choice C) may pose safety hazards and not directly impact cost savings.

Correct Answer: A

Rationale: Prolonged bed rest can lead to hypocalcemia due to decreased mobility and bone resorption. In this scenario, the low serum calcium level of 4.0 mg/dL is likely a result of decreased bone activity and calcium release due to prolonged bed rest. Renal insufficiency would more likely lead to hypercalcemia due to impaired excretion of calcium by the kidneys. Hyperparathyroidism is characterized by increased calcium levels as a result of excess parathyroid hormone. Excessive ingestion of vitamin D can cause hypercalcemia by increasing intestinal absorption of calcium.

Correct Answer: B

Rationale: The major concern about the health-care system in the United States is the quality of care provided. While disease prevention and collaborative care are important aspects, the primary focus of concern is ensuring that the care delivered meets high standards in terms of effectiveness, safety, and patient outcomes. Reduction in hospital-acquired drug-resistant infections, although relevant, is not the primary concern when evaluating the overall quality of healthcare services.

Correct Answer: B

Rationale: High doses of prednisone are commonly prescribed for giant cell arthritis to reduce inflammation. Aspirin is not typically used for this condition. Methotrexate is more commonly used for conditions like rheumatoid arthritis, not giant cell arthritis. Albuterol is a bronchodilator used for respiratory conditions, not for giant cell arthritis.

Correct Answer: B

Rationale: Rotating injection sites when administering insulin helps prevent insulin lipodystrophy, which is the abnormal distribution of fat at injection sites. Insulin edema (choice A) is not prevented by rotating injection sites; it is characterized by swelling at the site of insulin injection due to increased capillary permeability. Insulin resistance (choice C) is a condition where the body's cells become less responsive to insulin, and rotating injection sites does not directly prevent this. Systemic allergic reactions (choice D) are not specifically prevented by rotating injection sites; they are related to an allergic response to insulin.

Correct Answer: C

Rationale: A computer hacking episode is considered an internal disaster as it disrupts the internal operations of the healthcare facility, compromising data security and potentially impacting patient care. Choices A, B, and D do not directly relate to internal disasters in a healthcare setting. A patient fall is a patient safety issue, the massive spread of pneumonia is a public health concern, and unexpected staff absences due to illness may affect staffing levels but are not typically classified as internal disasters.

Correct Answer: B

Rationale: The correct answer is B. The Patient Protection and Affordable Care Act expanded school-based health centers to provide additional healthcare services to students. Choice A is incorrect because the creation of national health insurance exchanges was a key provision of the Affordable Care Act, but it was not the only change enacted by the legislation. Choice C is incorrect as while the Affordable Care Act did include provisions for free preventative services for certain groups, it was not applicable to all individuals. Choice D is incorrect as the Act did not specifically address medically managed clinics eligible for federal funding.
