Pediatric CCRN Practice Questions Questions
Question 1 of 5
A complete blood count is commonly performed before a client goes into surgery. What does this test seek to identify?
Correct Answer: C
Rationale: A complete blood count (CBC) is a common blood test that provides important information about the types and numbers of cells in the blood, such as red blood cells, white blood cells, and platelets. The primary purpose of performing a CBC before surgery is to identify any abnormalities in the blood that could affect the patient's ability to undergo the surgical procedure safely. Abnormally low hematocrit (HCT) and hemoglobin (Hb) levels indicated by a CBC may suggest anemia, which could impact the patient's ability to tolerate surgery and anesthesia. Anemia can result in decreased oxygen delivery to tissues and organs, leading to potential complications during surgery. Therefore, identifying low HCT and Hb levels through a CBC allows healthcare providers to take appropriate measures to address and manage the condition before proceeding with surgery.
Question 2 of 5
Which of the following disorders leads to cyanosis from deoxygenated blood entering the systemic arterial circulation?
Correct Answer: D
Rationale: Tetralogy of Fallot is a congenital heart defect characterized by four primary abnormalities: pulmonary stenosis, ventricular septal defect, overriding aorta, and right ventricular hypertrophy. Due to the pulmonary stenosis, less blood reaches the lungs to be oxygenated, resulting in deoxygenated blood entering the systemic arterial circulation. This leads to cyanosis, which is often referred to as "Tet spells" in these patients. Cyanosis is the bluish discoloration of the skin and mucous membranes caused by the presence of deoxygenated hemoglobin. The other conditions listed do not typically result in deoxygenated blood entering the systemic arterial circulation and causing cyanosis.
Question 3 of 5
A nurse is formulating a clinical question for evidence-based practice. Place in order the steps the nurse should use to clarify the scope of the problem and clinical topic of interest. Begin with the first step of the process and proceed ordering the steps ending with the final step of the process. Provide answer as lowercase letters separated by commas (e.g., a, b, c, d, e).
Correct Answer: c
Rationale: Population : The first step is to clearly define the population of interest for the clinical question. Identifying the specific population will help in formulating a focused and relevant question.
Question 4 of 5
Prenatal changes associated with maternal diabetes include all the following EXCEPT
Correct Answer: C
Rationale: Reduced milk production is not directly associated with maternal diabetes.
Question 5 of 5
Monthly examination (BSE) can help in early detection of breast CA. When do you perform BSE?
Correct Answer: A
Rationale: Performing monthly breast self-examination (BSE) after menstruation is recommended because during this time, the breasts are less likely to be swollen or tender, which can help to ensure a more accurate examination. Engaging in BSE on a regular basis can help individuals become familiar with their breast tissue and better recognize any changes that may occur. By performing BSE monthly after menstruation, individuals can actively monitor their breast health and potentially detect any abnormalities or signs of breast cancer at an early stage.
