A woman in active labor demonstrates persistent occiput posterior fetal position, contributing to prolonged labor and severe back pain. What nursing intervention should be prioritized to facilitate fetal rotation and optimize labor progress?

Correct Answer: A

Rationale: Placing the mother in a hands-and-knees position can help facilitate fetal rotation from occiput posterior to the desired occiput anterior position. This position utilizes gravity to assist in the repositioning of the baby, ultimately helping to alleviate back pain and promoting more efficient labor progress. It allows the baby's head to descend properly into the pelvis, potentially reducing the risk of a prolonged labor or the need for instrumental delivery. Additionally, being in this position can help the mother feel more comfortable and empowered during labor. Overall, assisting the mother into a hands-and-knees position is a non-invasive, low-risk intervention that can have a positive impact on both the mother and baby's well-being during labor.

Correct Answer: A

Rationale: The patient with a history of COPD presenting with increased dyspnea, cough productive of purulent sputum, and coarse crackles on auscultation is most likely experiencing an acute exacerbation of COPD. Acute exacerbations in COPD are defined as sustained worsening of the patient's respiratory symptoms beyond normal day-to-day variations, leading to a change in medication. Common triggers for exacerbations include respiratory infections, air pollution, and non-compliance with medications.

Correct Answer: C

Rationale: Calcium is essential for maintaining strong and healthy bones. Osteoporosis is a condition characterized by weakened bones, making them more prone to fractures. Consuming calcium-rich foods such as dairy products, leafy greens, and fortified foods can help prevent osteoporosis development. Additionally, incorporating calcium supplements under the guidance of a healthcare provider can further support bone health and reduce the risk of osteoporosis. Regular intake of adequate calcium is considered a crucial preventive measure for osteoporosis.

Correct Answer: A

Rationale: The presentation described with sudden-onset, painless vision loss, a cherry-red spot at the macula, and attenuated retinal vessels is classic for central retinal artery occlusion (CRAO). CRAO occurs when the central retinal artery, which supplies blood to the inner retinal layers, becomes occluded. The cherry-red spot is due to the exposure of the underlying choroid, which still appears red as it is not affected by the blockage. Attenuated retinal vessels and a pale retina may also be seen due to ischemia. In contrast, central retinal vein occlusion (choice B) presents with sudden painless vision loss, retinal hemorrhages, dilated retinal veins, and cotton-wool spots. Retinal detachment (choice C) typically presents with flashes, floaters, and a curtain-like shadow across the vision. Acute angle-closure glaucoma (

Correct Answer: A

Rationale: Toll-like receptors (TLRs) are a group of cellular receptors responsible for recognizing pathogen-associated molecular patterns (PAMPs), which are molecular components commonly found on pathogens like bacteria and viruses. When TLRs recognize these PAMPs, they initiate signaling pathways that trigger the innate immune response, leading to inflammation, antimicrobial defense, and the activation of adaptive immunity. B cell receptors (BCRs) and T cell receptors (TCRs) are involved in adaptive immune responses and recognize specific antigens rather than PAMPs. Fc receptors primarily bind to the Fc portion of antibodies and are involved in antibody-mediated immune responses. Thus, TLRs specifically play a critical role in sensing and responding to pathogens through the recognition of PAMPs.

Correct Answer: B

Rationale: Tilt back Claudia's head slightly would have been the correct action to prevent her from blinking during eye drop instillation. By tilting her head back, you create a more stable position for instilling the eye drops, reducing the likelihood of accidental contact with her eyelid. Additionally, tilting the head back slightly helps in making it easier for the drops to enter the eye and stay within the conjunctival sac, improving the efficacy of the medication.

Correct Answer: A

Rationale: According to RA 9482 or the Anti-Rabies Act of 2007, one of the key components of rabies prevention is to have dogs regularly vaccinated against rabies. This is a crucial step in reducing the risk of rabies transmission from dogs to humans. By ensuring that dogs are vaccinated, the likelihood of rabies exposure is significantly decreased. Additionally, proper vaccination also helps protect the health and well-being of the dogs themselves. Therefore, ensuring regular vaccination of dogs is an applicable and important statement regarding rabies post-exposure prophylaxis as mandated by the law.

Correct Answer: C

Rationale: In this situation, it is crucial for the nurse to inform the surgeon immediately and request corrective action. Maintaining a sterile field during surgical procedures is essential to prevent infections and ensure patient safety. Any break in sterile technique should be addressed promptly to prevent any potential harm to the patient. By informing the surgeon immediately, corrective action can be taken promptly to maintain the sterility of the surgical field and minimize the risk of complications. Reporting the incident to the surgeon also allows for immediate intervention and re-education of the team member involved in the break in sterile technique.

Correct Answer: A

Rationale: The patient is exhibiting signs and symptoms of alcohol withdrawal, such as tremors, diaphoresis, hyperactivity, elevated blood pressure, and tachycardia. Lorazepam, which is a benzodiazepine, is commonly used to manage alcohol withdrawal symptoms. It helps alleviate symptoms such as anxiety, agitation, tremors, and seizures by acting on the same brain receptors affected by alcohol. It has sedative, anxiolytic, and anticonvulsant properties which can help stabilize the patient and prevent potential complications of alcohol withdrawal, such as seizures. Haloperidol is an antipsychotic medication used for conditions like schizophrenia and acute psychosis; therefore, it would not be appropriate for alcohol withdrawal. Naloxone is used to reverse opioid overdose, and Benztropin is used to treat Parkinson's disease and extrapyramidal symptoms, so they are not indicated for alcohol
