The patient's diagnostic tests revealed he was positive for bacterial pneumonia. The MOST likely causative organism of this type of pneumonia is ______.

Correct Answer: B

Rationale: Streptococcus pneumoniae is the most common causative organism of bacterial pneumonia in adults. It is responsible for the majority of community-acquired pneumonia cases. Streptococcus pneumoniae is a gram-positive bacteria and is known to cause typical pneumonia characterized by sudden onset of high fever, productive cough with blood-tinged or rust-colored sputum, chest pain, and consolidation on chest imaging. Other organisms like Legionella pneumophila (choice A), Mycoplasma pneumoniae (choice C), and Haemophilus influenzae (choice D) can also cause pneumonia, but Streptococcus pneumoniae is the most likely culprit based on the patient's test results.

Correct Answer: C

Rationale: When selecting participants for a qualitative research study, it is important to choose individuals who are able to articulate and reflect on the phenomenon being studied. This is crucial for gathering in-depth and rich data that can provide valuable insights for the study. Participants who can express their experiences, thoughts, and feelings clearly will allow the researcher to delve deeper into the research objectives and gain a more comprehensive understanding of the phenomenon under investigation. Selecting individuals with the ability to articulate and reflect ensures that the data collected will be meaningful and contribute significantly to the research findings. It is essential for qualitative researchers to prioritize such participants who can best meet the objectives of the study by offering detailed and insightful perspectives.

Correct Answer: D

Rationale: The nurse should prioritize positioning the patient in a left lateral decubitus position during gastric lavage to ensure procedural effectiveness. This position helps to promote optimal drainage of fluid and gastric contents. Placing the patient in a left lateral position allows gravity to assist in the passage of fluid and prevents the risk of aspiration. It also helps to minimize the risk of complications such as reflux of lavage fluid into the respiratory tract. Proper positioning is essential in enhancing the success of the gastric lavage procedure and promoting patient safety.

Correct Answer: A

Rationale: The presentation of a palpable, non-tender mass in the right neck, just below the angle of the mandible, along with ultrasound imaging findings of a well-defined, hypoechoic lesion with cystic components, is classic for a branchial cleft cyst. Branchial cleft cysts are congenital anomalies that arise from remnants of the branchial clefts or pouches during embryonic development. They are typically located along the anterior border of the sternocleidomastoid muscle, just below the mandible. Ultrasound imaging often shows a cystic lesion with well-defined borders and hypoechoic content, which is consistent with the described findings. Thyroglossal duct cysts usually present as midline neck masses that move with swallowing or tongue protrusion, not in the location described in the scenario. Lymphadenopathy would present as enlarged lymph nodes that may be tender and associated with systemic symptoms.

Correct Answer: B

Rationale: In a patient with chronic kidney disease presenting with metabolic acidosis, the compensatory mechanism the body is most likely to employ to normalize pH is increased bicarbonate reabsorption in the kidneys. The kidneys play a crucial role in maintaining acid-base balance by regulating bicarbonate levels in the blood. In metabolic acidosis, there is an excess of non-volatile acids in the body, leading to a decrease in blood pH. To compensate for this acidosis, the kidneys increase the reabsorption of filtered bicarbonate ions from the renal tubules back into the blood. This process helps to raise the bicarbonate levels in the blood, which in turn helps to neutralize excess hydrogen ions and restore the blood pH towards normal levels. Hyperventilation (A) is a compensatory mechanism for respiratory acidosis, not metabolic acidosis. Increased renal excretion of hydrogen ions (C) and decreased renal excretion of bicarbonate ions

Correct Answer: B

Rationale: The constellation of severe lower abdominal pain, fever, and vaginal discharge in a pregnant woman raises suspicion for pelvic inflammatory disease (PID). Cervical motion tenderness and adnexal tenderness are classic physical exam findings for PID. The presence of bilateral adnexal masses further supports the diagnosis, as PID can lead to the formation of tubo-ovarian abscesses. Ectopic pregnancy may present with similar symptoms but is less likely in this case as bilateral adnexal masses suggest a more diffuse inflammatory process. Placenta previa would typically present with painless vaginal bleeding in the third trimester, which is not consistent with the symptoms described. Ovarian torsion would present with sudden severe unilateral lower abdominal pain and is less likely to involve both ovaries simultaneously.

Correct Answer: A

Rationale: The client is exhibiting signs and symptoms of respiratory alkalosis. When a person is experiencing respiratory alkalosis, there is an excessive loss of carbon dioxide (CO2) from the body, leading to elevated blood pH. The marked increase in the rate and depth of respirations as well as symptoms of anxiety, restlessness, and irritability are characteristic of respiratory alkalosis. This condition can be caused by hyperventilation, anxiety, or fever, which result in excessive elimination of CO2 from the body, leading to an imbalance in the acid-base status. Treatment for respiratory alkalosis involves addressing the underlying cause, such as providing reassurance to decrease anxiety or managing the breathing pattern to normalize CO2 levels.

Correct Answer: C

Rationale: Anticonvulsant medications, such as phenytoin and phenobarbital, can interfere with pregnancy tests by affecting the levels of human chorionic gonadotropin (hCG) in the body. HCG is the hormone detected in pregnancy tests. These medications may potentially lead to a false-negative result on a pregnancy test for women who are actually pregnant. Therefore, in the case of Almira, who is 6 months pregnant and taking anticonvulsant medication due to the risk of producing a false-negative pregnancy test result, healthcare providers should consider other clinical indicators, such as abdominal cramps and vaginal spotting, to assess her pregnancy status.

Correct Answer: A

Rationale: Participating in professional organizations can provide Nurse Bea with numerous opportunities to network with other professionals in the field, stay updated with the latest trends and developments in nursing, access resources for professional growth, and even participate in leadership roles within the organization. Being active in a professional organization can help Nurse Bea build her professional profile, gain recognition, and open up possibilities for career advancement and opportunities for collaboration and learning from peers. It can also help her stay connected with the broader nursing community and enhance her visibility within the field. Engaging with a professional organization is a valuable way for Nurse Bea to enhance her career alongside pursuing further education.
