As a QA nurse, which of the following can Nurse Jen adopts as a concurrent evaluation of patient's outcomes in the unit? I Direct observation of patient's condition. II Patient's interview in the unit. III Face to face interview with nursing staff. IV Nursing audit from the patient's chart.

Correct Answer: A

Rationale: As a QA nurse, Nurse Jen can adopt concurrent evaluation methods to assess patient outcomes in the unit. The most appropriate options for concurrent evaluation are Face to face interview with nursing staff (III) and Nursing audit from the patient's chart (IV).

Correct Answer: A

Rationale: An open chest wound, also known as a sucking chest wound, can lead to a collapsed lung and respiratory distress. Immediate management involves sealing the wound to prevent air from entering the pleural space and further compromising the patient's respiratory function. Applying a sterile dressing over the wound helps to prevent contamination and occluding the wound with an airtight covering, such as an occlusive dressing, can effectively reduce the risk of a tension pneumothorax, a serious complication that can arise from a sucking chest wound. These interventions help to stabilize the patient's condition and improve the chances of a successful recovery. Administering supplemental oxygen, though beneficial, would be secondary to the primary management of sealing the chest wound. Providing emotional support is important but addressing the physical emergency takes precedence. Elevating the patient's legs would not be appropriate in managing an open chest wound.

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: B

Rationale: The presentation of knee pain and swelling following a fall onto a flexed knee, along with a palpable effusion and tenderness along the joint line, is highly suggestive of a meniscus injury. The McMurray's test specifically evaluates for meniscal tears. In this case, the presence of pain and clicking with passive knee flexion and internal rotation indicates a medial meniscus tear as the most likely diagnosis. Patellar tendinitis usually presents with anterior knee pain that is worsened by activities such as jumping or running. Lateral collateral ligament (LCL) sprain typically presents with lateral knee pain and instability. Quadriceps tendon rupture would present with significant weakness and inability to fully extend the knee, which is not described in this scenario.

Correct Answer: D

Rationale: The principles of guidance in handling Richard involve understanding and addressing the behaviors and needs of the child, such as controlling temper tantrums, basing expectations within the child's limitations, and acceptance of certain behaviors like masturbation as normal but to be discouraged in public. However, reinforcing the correct use of language is not typically included as a principle specifically in handling Richard. Therefore, this choice is NOT included among the principles of guidance in this context.

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: In quantitative research, randomness plays a crucial role in eliminating bias. Random sampling ensures that every individual or element in the population has an equal chance of being selected for the study. This helps in reducing the possibility of bias creeping into the results due to selective sampling or favoritism towards certain groups. By using random sampling methods, researchers can increase the generalizability of their findings and have a higher level of confidence that the results are unbiased and representative of the entire population. Therefore, randomness is a key mechanism to eliminate bias in quantitative research studies.

Correct Answer: C

Rationale: The nurse should prioritize removing the old dressing and applying a new dressing using sterile technique to minimize the risk of infection during a central venous catheter (CVC) dressing change. This is because the most critical step in preventing infection is maintaining a clean and sterile environment around the CVC insertion site. By using sterile technique, the nurse can reduce the introduction of microorganisms that could potentially lead to infection. Wearing sterile gloves and cleaning the insertion site with an alcohol-based antiseptic solution are important steps as well, but the key priority lies in applying the new dressing using sterile technique to prevent contamination and reduce the risk of infection.

Correct Answer: C

Rationale: Intracerebral hemorrhage occurs when there is bleeding directly into the brain tissue, often due to conditions such as hypertension or vascular malformations. The sudden-onset severe headache, altered mental status, and focal neurological deficits described in the patient are typical symptoms of an intracerebral hemorrhage. The location of the hemorrhagic lesion within the right basal ganglia corresponds to the clinical presentation. Ischemic stroke, subarachnoid hemorrhage, and transient ischemic attack (TIA) typically have different presentations and imaging findings compared to an intracerebral hemorrhage. Therefore, in this scenario, intracerebral hemorrhage is the most likely cause of the patient's symptoms.
