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: A

Rationale: Aplastic anemia is a condition characterized by a reduction in the number of all three blood cell types: red blood cells, white blood cells, and platelets. The patient's presentation of bone pain, fatigue, frequent infections, pancytopenia (decreased counts of all blood cell types), hypocellular bone marrow (reduced cellularity in the bone marrow), and absence of reticulocytes is indicative of aplastic anemia.

Correct Answer: B

Rationale: Dental caries, commonly known as tooth decay, is characterized by the irreversible demineralization of the enamel and dentin due to acids produced by bacterial activity. This process leads to cavitation and destruction of the tooth structure, ultimately resulting in the formation of a cavity. Gingivitis is inflammation of the gums, periodontitis is inflammation and infection of the supporting structures of the teeth (gums, bone, and ligaments), and a dental abscess is a collection of pus in the tissues surrounding the tooth, none of which are specifically related to the irreversible demineralization of enamel and dentin seen in dental caries.

Correct Answer: A

Rationale: An adequate contraction pattern during labor is characterized by regular contractions occurring at a frequency of three to 5 contractions in a 10-minute period, with resultant cervical dilatation. This pattern indicates efficient uterine activity that is helping to progress labor by dilating the cervix. In option A, the contractions are occurring at an appropriate frequency and are resulting in cervical dilatation, making it the correct choice for indicating an adequate contraction pattern.

Correct Answer: A

Rationale: The most likely causative agent in this scenario is Plasmodium falciparum, which is the parasite that causes malaria. The symptoms of fever, chills, headache, and myalgia following a camping trip are highly suggestive of malaria, especially if the patient has thrombocytopenia and leukopenia. Plasmodium falciparum is known to cause severe malaria with complications such as thrombocytopenia and leukopenia. The other options, Trypanosoma cruzi, Borrelia burgdorferi, and Leishmania donovani, do not typically present with all of the symptoms described and are not associated with the laboratory findings of thrombocytopenia and leukopenia.

Correct Answer: D

Rationale: Negligence refers to the failure to take proper care in doing something. In this scenario, the nurse failed to exercise the standard of care expected in placing a heating pad directly on Mr. C's lower leg, knowing his history of peripheral vascular disease. This failure led to a burn and subsequent infection that required a skin graft for treatment. The actions of the nurse were negligent as they did not meet the expected standard of care, resulting in harm to the patient. This situation does not fit the definition of assault, malpractice, or vicarious liability, making negligence the most appropriate choice.

Correct Answer: A

Rationale: Corticosteroids, commonly used in the treatment of nephrotic syndrome, can cause various side effects. One of the common side effects of corticosteroids is a loss of appetite. Patients receiving corticosteroid therapy may experience a decreased desire to eat, leading to reduced food intake. Monitoring for changes in appetite is important as a decrease in food intake can impact overall nutrition and may affect the patient's response to treatment. It is essential for the nurse to watch for this side effect to address any potential nutritional concerns and collaborate with the healthcare team to optimize the patient's care.

Correct Answer: B

Rationale: Marlene opening up to the nurse about their financial difficulty indicates that she feels comfortable enough to share personal information with the nurse. This signals the establishment of a trusting relationship between Marlene and the nurse, as Marlene feels safe and supported enough to disclose sensitive information. Building trust is a crucial aspect of any professional relationship, especially in healthcare settings, as it fosters open communication, encourages honesty, and ultimately leads to better outcomes for the patient. It is an essential foundation for providing effective care and support to individuals in need.

Correct Answer: C

Rationale: The public health nurse's participation in the essential services that are relevant and accessible to the family and the community includes informing, educating, and empowering the people about health. This is a critical aspect of the role of a public health nurse as it involves engaging with individuals and communities to provide them with accurate information about health promotion, disease prevention, and access to healthcare services. By informing, educating, and empowering the people about health, public health nurses can help individuals and communities make informed decisions about their health and well-being, leading to improved health outcomes and overall community health.
