If a research study involves an intervention and "blinding" which research design is being referred to?
- A. Non-descriptive
- B. Experimental
- C. Phenomenological
- D. Descriptive
Correct Answer: B
Rationale: The research design being referred to in the question is an experimental design. An experimental study involves the manipulation of an independent variable, which is the intervention in this case, to determine its effect on a dependent variable. "Blinding" in research refers to the practice of withholding information about the intervention from certain individuals involved in the study, such as researchers, participants, or outcome assessors. Blinding is commonly used in experimental studies to reduce bias and ensure the integrity of the study results. This combination of intervention and blinding is a hallmark of experimental research designs.

A pregnant woman presents with severe abdominal pain and vaginal bleeding at 8 weeks gestation. On examination, the cervix is closed. Which of the following conditions is the most likely cause of these symptoms?
- A. Ectopic pregnancy
- B. Threatened abortion
- C. Placenta previa
- D. Gestational trophoblastic disease
Correct Answer: B
Rationale: In a pregnant woman presenting with severe abdominal pain and vaginal bleeding at 8 weeks gestation with a closed cervix, the most likely cause of these symptoms is a threatened abortion. A threatened abortion is a common complication of early pregnancy characterized by vaginal bleeding and lower abdominal pain without cervical dilation. The cervix remains closed, indicating that the pregnancy is still intact but at risk of potential miscarriage. Placenta previa typically presents with painless vaginal bleeding in the second or third trimester, whereas ectopic pregnancy usually presents with abdominal pain and vaginal bleeding in the setting of a closed cervix but is less likely at 8 weeks gestation. Gestational trophoblastic disease is a rare cause of vaginal bleeding in pregnancy and typically presents in the first trimester with signs of hyperemesis gravidarum, uterine enlargement, and elevated β-hCG levels.
Which of the following structures is responsible for storing and concentrating bile produced by the liver until it is needed for digestion?
- A. Liver
- B. Gallbladder
- C. Pancreas
- D. Spleen
Correct Answer: B
Rationale: The gallbladder is the structure responsible for storing and concentrating bile produced by the liver until it is needed for digestion. Bile is a digestive fluid that helps in the breakdown of fats during the digestive process. When food containing fats enters the small intestine, the gallbladder contracts and releases bile into the small intestine to aid in the digestion and absorption of fats. The gallbladder acts as a reservoir for bile, storing it until it is needed for digestion.
A woman in active labor experiences frequent and intense uterine contractions with minimal rest intervals, leading to maternal fatigue and decreased fetal oxygenation. What maternal condition should the nurse assess for that may contribute to this abnormal labor pattern?
- A. Maternal dehydration
- B. Uterine hyperstimulation
- C. Pelvic outlet obstruction
- D. Maternal exhaustion
Correct Answer: B
Rationale: Uterine hyperstimulation, also known as tachysystole, is a condition characterized by frequent and intense uterine contractions with minimal rest intervals. This can lead to maternal fatigue and decreased fetal oxygenation due to the insufficient time for the uterus to relax and refill with oxygenated blood between contractions. Uterine hyperstimulation can be caused by various factors such as excessive use of uterotonics (oxytocin or prostaglandins), improper labor induction techniques, or maternal conditions like previous uterine surgery. It is essential for the nurse to assess for signs of uterine hyperstimulation and take appropriate interventions to prevent potential complications for both the mother and the baby.

- C. I, III, and IV

Which of the following is a primary consideration in planning for her care?
- A. To prevent problems related to immobility
- B. To prevent infection
- C. Planning for client`s eventual inability communicate
- D. To prevent complications
Correct Answer: A
Rationale: When planning for a client's care, a primary consideration is to prevent problems related to immobility. Immobility can lead to a range of complications such as pressure ulcers, muscle weakness, joint contractures, and decreased circulation. To maintain the client's overall health and well-being, it is essential to address mobility issues and implement strategies to prevent complications associated with immobility. By prioritizing interventions that promote movement and prevent immobility-related problems, the client's quality of life can be improved and potential health risks mitigated.
