Correct Answer: B

Rationale: The correct answer is B: 20-Gauge. The smaller the gauge number, the larger the diameter of the catheter. Blood transfusions typically require a larger catheter size to prevent hemolysis and ensure proper flow. A 20-Gauge catheter is larger than 22-Gauge, 18-Gauge, and 12-Gauge, making it suitable for administering blood. 22-Gauge is too small and can cause hemolysis, 18-Gauge is smaller than the recommended size for blood transfusions, and 12-Gauge is too large and can cause damage to the vein.

Correct Answer: C

Rationale: The correct answer is C: Food and water. Typhoid fever is primarily transmitted through contaminated food and water by the bacterium Salmonella typhi. The bacteria are shed in the feces of infected individuals and can contaminate water sources or food prepared with contaminated water. This transmission route aligns with the typical epidemiology of typhoid fever outbreaks. Now, let's discuss why the other choices are incorrect: A: A vector - Typhoid fever is not transmitted by a vector such as mosquitoes or ticks. B: Blood and body fluids - Typhoid fever is not typically spread through blood or body fluids but rather through ingestion of contaminated food or water. D: Air - Typhoid fever is not an airborne disease and is not transmitted through the air.

Correct Answer: A

Rationale: Precipitous labor is characterized by rapid cervical dilation and descent of the fetal presenting part, leading to a shortened labor duration of less than 3 hours. This rapid progression can increase the risk of maternal complications, such as postpartum hemorrhage. Postpartum hemorrhage is defined as excessive bleeding of more than 500 ml after vaginal delivery or more than 1000 ml after cesarean delivery. The rapid delivery in precipitous labor can result in inadequate uterine contractions after delivery, leading to poor uterine tone and potential postpartum hemorrhage due to uterine atony. Therefore, the nurse should anticipate postpartum hemorrhage as a potential maternal complication in a woman experiencing precipitous labor.

Correct Answer: B

Rationale: In this scenario, the pregnant woman is presenting with severe abdominal pain, passage of tissue, and cervical dilation with products of conception protruding through the cervical os at 12 weeks gestation. These are classic signs and symptoms of an incomplete abortion. Incomplete abortion occurs when not all of the products of conception are expelled from the uterus. It can present with vaginal bleeding, abdominal pain, cervical dilation, and passage of tissue. The management of incomplete abortion may involve expectant, medical, or surgical options depending on the clinical context and the patient's condition.

Correct Answer: C

Rationale: The correct answer is C: Hyponatremia. SSRI medications can lead to the syndrome of inappropriate antidiuretic hormone secretion (SIADH), causing hyponatremia. This occurs due to increased levels of serotonin affecting the hypothalamus, leading to excessive ADH release. Hyponatremia can result in neurological symptoms and must be closely monitored. A: Bradycardia is not a common adverse effect of SSRIs. B: Hyperkalemia is not typically associated with SSRIs. D: Hypertension is not a common adverse effect of SSRIs; they may actually lower blood pressure.
