The nurse is assessing a patient who is diagnosed with tuberculosis. Which assessment finding correlates with this diagnosis?

Rhonchi

weight gain

Hemoptysis

Frothy sputum

Answer and Explanation

The Correct Answer is C

A.   Rhonchi are abnormal lung sounds that result from obstruction or secretions in larger airways. They are more commonly associated with conditions like chronic bronchitis or COPD rather than tuberculosis. While TB can lead to various lung sounds, rhonchi are not a hallmark of the disease.
B.   Weight gain is generally not associated with tuberculosis. In fact, TB often leads to weight loss due to factors like loss of appetite, increased metabolic demand, and systemic effects of the infection. Patients with active TB frequently present with cachexia (wasting) or weight loss, not weight gain.
C.   Hemoptysis, or coughing up blood, is a significant and classic symptom associated with tuberculosis, especially in cases involving pulmonary TB. It occurs due to the erosion of blood vessels in the lungs as the disease progresses. This makes it a strong correlating finding with a diagnosis of tuberculosis.
D.   Frothy sputum is more characteristic of pulmonary edema or conditions such as congestive heart failure. In tuberculosis, sputum may be mucoid or purulent and sometimes contains blood, but it is not typically described as frothy.

Correct Answer is A

Explanation

A. Beta-adrenergic agents (often called bronchodilators) work by stimulating beta-2 adrenergic receptors in the airway smooth muscle, leading to relaxation of the muscles and dilation of the airways. This helps improve airflow and relieve symptoms of asthma.
B. A beta-adrenergic agent should ideally increase peak expiratory flow (PEF) by dilating the airways and improving airflow, not decrease it.
C. This is not a direct action of beta-adrenergic agents. While some medications (like mucolytics or certain expectorants) can thin secretions, beta-adrenergic agents primarily focus on bronchodilation and do not significantly affect the viscosity of respiratory secretions.
D. While beta-adrenergic agents can sometimes cause mild tachycardia (increased heart rate) as a side effect, they are not intended to increase the respiratory rate directly. The primary goal of these medications is to improve airway patency rather than change the rate of breathing.

Correct Answer is ["21"]

Explanation

Convert infusion time to minutes:

2 hours * 60 minutes/hour = 120 minutes

Calculate the total number of drops:

250 mL * 10 gtt/mL = 2500 gtt

Calculate the flow rate:

Flow rate = Total number of drops / Infusion time Flow rate = 2500 gtt / 120 minutes

Flow rate ≈ 20.83 gtt/min

Rounding to the nearest drop, the flow rate for the infusion of packed red blood cells is 21 gtt/min.
