The physician orders a unit of packed red blood cells (PRBC) to infuse in 2 hours. The unit contains 250 mL. The blood tubing administration set has a drop factor of 10 gtt/mL. The flow rate for the infusion of packed red blood cell is gtt/min. (Round to the nearest drop)

A. This statement is not necessarily true for every situation. While close contacts of a person with active TB may need to be tested and could receive preventive treatment (especially if they are at high risk), not all family members will automatically need to take medications.
B. A standard treatment regimen for active pulmonary TB typically lasts at least 6 months, and sometimes longer, depending on the specific circumstances (e.g., drug resistance, extent of disease). Consistent adherence to the medication regimen is crucial to ensure effective treatment and prevent the development of drug-resistant TB.
C. The Mantoux test (or tuberculin skin test) may remain positive even after successful treatment for TB, as it indicates past exposure rather than active disease. The decision to discontinue medications is based on clinical and microbiological evaluations, not solely on the Mantoux test result.
D. While it is crucial for the client to complete the full course of prescribed medications, they do not need to take them for life. Treatment typically lasts for 6 to 9 months, and clients should not continue medication indefinitely. It is essential to emphasize adherence to the treatment regimen but also to note that it is finite.

A. Primary hypertension, also known as essential hypertension, is characterized by high blood pressure without an identifiable or specific medical cause. It is the most common type of hypertension, and its development is thought to result from a combination of genetic, environmental, and lifestyle factors.
B. This statement is misleading. While hypertension can be severe, primary hypertension is not defined by its severity or immediate life-threatening nature. Instead, primary hypertension can range from mild to severe, but the key characteristic is the absence of a specific underlying cause.
C. While treating hypertension is important, the term "essential" in primary hypertension refers to its lack of a known cause, not the urgency or necessity of treatment. This option could confuse the terminology as it does not accurately define the type of hypertension.
D. This statement describes secondary hypertension, which occurs as a result of another medical condition (e.g., kidney disease, hormonal disorders). Primary hypertension, in contrast, does not have a direct identifiable cause.
