Correct Answer: B

Rationale: Famotidine belongs to a class of medications known as H2 blockers which work to reduce the production of stomach acid. Antacids, on the other hand, work by neutralizing stomach acid. Taking antacids in conjunction with famotidine can decrease the effectiveness of famotidine as they can interfere with its absorption. Therefore, it is important for the patient to avoid taking antacids while on famotidine therapy to ensure optimal treatment outcomes for gastric acid suppression.

Correct Answer: C

Rationale: Ventricular tachycardia (VT) is a potentially life-threatening arrhythmia characterized by wide QRS complexes and absence of P waves on electrocardiogram (ECG). Patients with VT may present with symptoms such as chest pain, dyspnea, and syncope due to reduced cardiac output and ineffective pumping of the heart. VT is a serious condition that requires prompt treatment to prevent hemodynamic compromise and potential cardiac arrest. Stable angina typically presents with chest pain that is provoked by exertion and relieved by rest or nitroglycerin. Atrial fibrillation is characterized by an irregularly irregular rhythm with absent P waves on ECG. Supraventricular tachycardia typically presents with a narrow QRS complex on ECG.

Correct Answer: D

Rationale: The correct approach for formulating statements of findings in a study is to extract meanings and themes from significant statements. This involves analyzing the data collected, identifying patterns or themes that emerge from the responses, and then formulating statements that encapsulate these findings. By doing so, the researcher can accurately capture the essence of the data and present meaningful conclusions based on the analysis. This process goes beyond merely summarizing or describing the responses and delves deeper into the interpretations and implications of the findings.

Correct Answer: B

Rationale: Mastitis is typically caused by bacterial infection, with predisposing factors including milk stasis (I) and nipple trauma (II). Milk stasis occurs when milk is not effectively removed from the breast, leading to a build-up that can block ducts and predispose to infection. Nipple trauma, such as cracks or damage, can provide entry points for bacteria to infect the breast tissue. Factors like using alcohol in cleaning nipples (III) and the baby's sitting position (IV) are not directly associated with the development of mastitis.

Correct Answer: C

Rationale: Republic Act 9173, also known as the Philippine Nursing Act of 2002, mandates the compulsory immunization of children below 8 years. This law ensures that young children receive necessary vaccines to protect them from preventable diseases and promote public health. RA 9173 is a significant legislation that highlights the importance of immunization in safeguarding the well-being of children in the Philippines.
