Question 1 of 5
One tablet of chlorine is efficient to chlorinate how many litres of water?
Correct Answer: B
Rationale: Chlorine tablets disinfect water by releasing hypochlorous acid to kill pathogens. Standard tablets (e.g., 1 mg chlorine) are designed to treat specific volumes based on concentration needs (typically 0.5-2 mg/L). Choice A (10 L) underestimates common tablet capacity, while C (30 L) and D (40 L) exceed typical single-tablet efficacy without specifying tablet strength. B (20 L) aligns with widely used chlorine tablets (e.g., NaDCC) for household water purification, achieving safe levels per WHO guidelines. Nurses educating communities on water safety must clarify dosage, ensuring effective pathogen control without overdose, making 20 L the correct, practical answer.
Question 2 of 5
An infant is born precipitously outside the labor room. What should the nurse do first?
Correct Answer: B
Rationale: Precipitous birth outside controlled settings demands urgent action. Tying/cutting the cord (choice A) is secondary; delay poses no immediate risk unless bleeding occurs. Establishing an airway (choice B) is first, as newborns must breathe independently clearing mucus or stimulating crying ensures oxygenation, critical within the golden minute. Checking the fundus (choice C) assesses maternal bleeding, a later priority. Transport (choice D) follows stabilization. B is correct, per neonatal resuscitation guidelines. Nurses clear airways, warm the infant, and then address cord and maternal needs, ensuring survival.
Question 3 of 5
The coronary vessels, unlike any other blood vessels in the body, respond to sympathetic stimulation by
Correct Answer: B
Rationale: The coronary vessels are unique because they respond to sympathetic stimulation with vasodilatation, unlike most other blood vessels which constrict. Sympathetic stimulation activates the fight-or-flight response, increasing heart rate and oxygen demand. To meet this demand, the coronary arteries dilate to supply more blood to the heart muscle. Vasoconstriction (A) is incorrect as it would reduce blood flow, countering the heart's needs during stress. Decreases in force of contractility (C) or cardiac output (D) are unrelated to the vascular response and pertain more to myocardial function, not the coronary vessels' behavior. This vasodilatation is mediated by beta-adrenergic receptors, ensuring adequate perfusion during heightened activity, making B the correct choice.
Question 4 of 5
What stress response can you expect from a patient with blood sugar of 50 mg/dl?
Correct Answer: C
Rationale: A blood sugar level of 50 mg/dl indicates hypoglycemia, a stress state triggering the body's fight-or-flight response. The client will appear restless due to the brain's reliance on glucose; low levels cause agitation as a protective mechanism to signal distress. The body attempts to increase glucose via glycogenolysis and gluconeogenesis (opposite of A), so decreasing glucose further is incorrect. Halting sex hormone release (B) occurs in chronic stress, not acute hypoglycemia. Blood pressure may rise (D) due to catecholamine release, but restlessness is the most immediate and observable response in this acute scenario, aligning with early stress symptoms. Thus, C is correct as it directly reflects the patient's presentation during a hypoglycemic crisis.
Question 5 of 5
Nurse Aida has seen her patient, Roger for the first time. She establish a contract about the frequency of meeting and introduce to Roger the expected termination. She started taking baseline assessment and set interventions and outcomes. On what phase of NPR Does Nurse Aida and Roger belong?
Correct Answer: B
Rationale: Nurse Aida and Roger are in the Orientation phase (B). This stage involves the first meeting, establishing a contract (meeting frequency, termination expectations), and initial assessments to set goals. Pre-Orientation (A) is before contact, reviewing records. Working (C) focuses on implementing plans, and Termination (D) ends the relationship. Orientation, per Peplau, sets the foundation with trust and planning, matching Aida's actions, making B correct.
