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.

To remove the ingested poisonous substance, the physician ordered a gastric lavage. What is the role of the nurse immediately prior to the procedure?
- A. Get the right size of the nasogastric tube
- B. Remind parents to be careful next time
- C. Obtain an informed consent immediately
- D. Tell the parent that they are negligent
Correct Answer: A
Rationale: Prior to a gastric lavage procedure, it is essential for the nurse to ensure the correct size of the nasogastric tube is selected. The appropriate size of the tube will allow for effective removal of the ingested poisonous substance during the procedure. Proper sizing also helps in preventing complications such as injury to the gastrointestinal tract or inadequate removal of the substance. This step is crucial for the safe and successful completion of gastric lavage. Reminding parents to be careful, obtaining informed consent immediately, or accusing them of negligence are not immediate responsibilities of the nurse in this context.
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.
You informed the mother about the normal psychosocial development of pre schoolers. She correctly understands your health teaching if she verbalizes that ________.
- A. He may have temper tantrums resulting from his frustration im watching to do everything for himself.
- B. He continues to react to separation from his parents.
- C. He son is more active with his parents and tends to be a bit selfish with his toys.
- D. He may tend exaggerate, boast, and tattle on others.
Correct Answer: A
Rationale: Option A indicates an understanding of the normal psychosocial development of preschoolers. It reflects the fact that during this stage, children may demonstrate frustration and have temper tantrums as they strive for independence and attempt to do things by themselves. This behavior is a common part of their development as they learn self-control, autonomy, and decision-making skills. The other options do not directly relate to normal preschooler development but rather touch upon separate issues such as separation anxiety, possessiveness, and social behaviors that are not necessarily abnormal for preschoolers.
A patient with suspected acute exacerbation of asthma presents with severe dyspnea, accessory muscle use, and inability to speak in full sentences. Which of the following interventions is most appropriate for assessing the severity of the patient's asthma exacerbation and guiding management decisions?
- A. Peak expiratory flow rate (PEFR) measurement
- B. Arterial blood gas (ABG) analysis
- C. Chest X-ray
- D. Clinical assessment using standardized severity scores
Correct Answer: D
Rationale: In the scenario described, the patient is presenting with severe symptoms of acute exacerbation of asthma, including severe dyspnea, accessory muscle use, and inability to speak in full sentences. In such cases, the most appropriate intervention for assessing the severity of the asthma exacerbation and guiding management decisions is a clinical assessment using standardized severity scores.
A patient asks the nurse about alternative treatment options for their condition. What is the nurse's best response?
- A. Dismiss the patient's question and assert that the current treatment plan is the only option.
- B. Provide the patient with information about alternative treatment options, including benefits and risks.
- C. Ignore the patient's question and redirect the conversation to a different topic.
- D. Tell the patient that alternative treatments are ineffective and should be avoided.
Correct Answer: B
Rationale: The nurse's best response when a patient asks about alternative treatment options is to provide the patient with information about those options, including their benefits and risks. It is important for the nurse to support the patient in their exploration of different treatment approaches and empower them to make informed decisions about their care. Dismissing the question, ignoring it, or discouraging alternative treatments are not appropriate responses and may hinder the patient's ability to make choices that align with their values and preferences. Therefore, providing information and facilitating an open discussion about alternative treatments is the most appropriate approach for the patient's best interest.
