In conducting a study on sleep, Nurse Trining was asked which of the types of research will be used should it involve collecting numerical data which is most often under considerable control. Her answer should be _________.
- A. Ichnographic
- B. Qualitative
- C. Phenomenological
- D. Quantitative
Correct Answer: D
Rationale: Quantitative research is the type of research that involves collecting numerical data, which can be easily quantified and analyzed statistically. It is characterized by its structured methodology, objectivity, and the ability to control variables to a considerable extent. In the context of a study on sleep, where data related to sleep patterns, duration, quality, etc., need to be measured and analyzed in a systematic manner, quantitative research would be the most appropriate choice. This type of research allows for a more precise understanding of the relationships and patterns within the data, providing valuable insights into the sleep-related factors being studied.

A patient with a history of Hodgkin lymphoma presents with fever, chills, and generalized malaise. Laboratory tests reveal pancytopenia, circulating Reed-Sternberg cells, and bone marrow involvement. Which of the following conditions is most likely to cause these findings?
- A. Autoimmune hemolytic anemia (AIHA)
- B. Myelodysplastic syndrome (MDS)
- C. Aplastic anemia
- D. Paraneoplastic syndrome
Correct Answer: D
Rationale: The patient is presenting with symptoms and laboratory findings consistent with a paraneoplastic syndrome related to Hodgkin lymphoma. In this case, the fever, chills, generalized malaise, pancytopenia, circulating Reed-Sternberg cells, and bone marrow involvement are all indicative of a paraneoplastic syndrome associated with Hodgkin lymphoma. Paraneoplastic syndromes are a group of disorders that are triggered by an abnormal immune response to a neoplasm, such as Hodgkin lymphoma, leading to various systemic manifestations.
Charting are important documents that are used in court proceedings a Nurse Chona should take note that the following entry recorded would be MOST defensible in court?
- A. Large bruises on thigh upon assessment.
- B. Patient fell out of bed when reaching out for medication.
- C. Burn on the back area observed upon auscultation.
- D. Patient drunk when seen in the Emergency Room.
Correct Answer: A
Rationale: Of the options provided, documenting objective, observable findings such as large bruises on the thigh upon assessment is the most defensible entry in court. This type of entry is based on the nurse's direct observation and assessment of the patient's physical condition, which can be corroborated by other healthcare providers or evidence. It provides clear, factual information without making assumptions or subjective judgments. In court, this type of documentation can help support the nurse's credibility and reliability as a witness.
During the postpartum assessment, a new mother reports experiencing mild cramping and uterine contractions while breastfeeding. What physiological process is responsible for these symptoms?
- A. Prolactin release
- B. Oxytocin release
- C. Estrogen surge
- D. Progesterone withdrawal
Correct Answer: B
Rationale: Oxytocin release is responsible for the mild cramping and uterine contractions experienced by the new mother while breastfeeding. When a baby suckles at the breast, it stimulates nerve endings that signal the release of oxytocin from the posterior pituitary gland. Oxytocin is a hormone that plays a crucial role in stimulating the contraction of the uterine muscles, helping the uterus to contract back to its pre-pregnancy size. This process, known as uterine involution, is essential for postpartum recovery and preventing excessive bleeding. Therefore, the new mother's experience of mild cramping and uterine contractions while breastfeeding is a normal physiological response mediated by the release of oxytocin.
A patient presents with chest pain that occurs at rest and is exacerbated by deep breathing or changes in body position. The pain improves with leaning forward. Which cardiovascular disorder is most likely responsible for these symptoms?
- A. Stable angina
- B. Unstable angina
- C. Pericarditis
- D. Myocarditis
Correct Answer: C
Rationale: Pericarditis is the inflammation of the pericardium, the sac surrounding the heart. Patients with pericarditis typically present with sharp chest pain that worsens with deep breathing, changes in body position, and coughing. The pain tends to improve when the patient leans forward. This characteristic symptom of pericarditis is known as "pleuritic" chest pain. In contrast, stable angina presents as predictable chest pain that occurs with exertion and is relieved by rest or medications. Unstable angina is characterized by chest pain that occurs at rest or with minimal exertion and is considered a medical emergency. Myocarditis involves inflammation of the heart muscle and may present with symptoms such as chest pain, but it does not typically have the characteristic of worsening with deep breathing or changes in body position.
A pregnant woman presents with vaginal bleeding and crampy abdominal pain at 22 weeks gestation. On examination, the cervix is dilated, and the amniotic sac is visible at the cervical os. Which of the following conditions is the most likely cause of these symptoms?
- A. Ectopic pregnancy
- B. Threatened abortion
- C. Placenta previa
- D. Incompetent cervix
Correct Answer: D
Rationale: Incompetent cervix, also known as cervical insufficiency, is the most likely cause of the symptoms described. Incompetent cervix is a condition where the cervix begins to dilate and efface prematurely, typically in the second trimester, without contractions or labor. This can lead to painless cervical dilation and bulging of the amniotic sac into the vagina, which can cause vaginal bleeding and crampy abdominal pain. It is a leading cause of second-trimester pregnancy loss. Treatment may involve a cervical cerclage, a surgical procedure where the cervix is stitched closed to provide additional support.
