Nokea
A patient presents with well-demarcated, erythematous plaques with silvery scales on the trunk and extensor surfaces of the limbs. The patient reports a family history of similar skin lesions. Which of the following conditions is most likely responsible for this presentation?
- A. Pityriasis rosea
- B. Psoriasis
- C. Erythema multiforme
- D. Lichen planus
Correct Answer: B
Rationale: The patient's presentation of well-demarcated, erythematous plaques with silvery scales on the trunk and extensor surfaces of the limbs is classic for psoriasis. Additionally, the family history of similar skin lesions further supports the diagnosis of psoriasis, as it is a condition with a genetic predisposition. Pityriasis rosea typically presents with a herald patch followed by oval, scaly lesions in a Christmas tree pattern. Erythema multiforme is characterized by target-like lesions. Lichen planus presents as purple, polygonal, flat-topped papules that may have fine white lines on their surface known as Wickham striae.

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?
- A. Assisting the mother into a hands-and-knees position
- B. Administering intravenous opioids for pain relief
- C. Preparing for immediate instrumental delivery
- D. Initiating continuous electronic fetal monitoring
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.
Which of the following interventions is most appropriate for a patient with a tension pneumothorax?
- A. Needle decompression
- B. Chest tube insertion
- C. High-flow oxygen therapy
- D. Incentive spirometry
Correct Answer: A
Rationale: A tension pneumothorax is a life-threatening condition where air accumulates in the pleural space and cannot escape, causing increased pressure in the chest cavity. This can lead to compression of the lung and major blood vessels, leading to inadequate oxygenation and circulation.
Nurse Roberto is aware that a client who has experienced cardiac arrest is MOST at risk for which of the following imbalances?
- A. Metabolic alkalosis
- B. Metabolic acidosis
- C. Respiratory alkalosis
- D. Respiratory acidosis
Correct Answer: D
Rationale: When a client experiences cardiac arrest, their breathing may become insufficient, leading to inadequate elimination of carbon dioxide (CO2) from the body. With reduced CO2 elimination, the level of CO2 in the bloodstream increases, causing respiratory acidosis. This imbalance is characterized by a decrease in blood pH along with an increase in CO2 levels in the blood, resulting in an acidic environment. Respiratory acidosis is the most common imbalance seen in clients who have experienced cardiac arrest, as impaired gas exchange impacts the body's ability to maintain proper acid-base balance.
The physician orders cromolyn sodium (nasal crom) for the client. The nurse instructs the client that the most effective administration schedule is ________.
- A. When manifestations peak only, with two or three doses per day
- B. At the start of the allergy season, with a dose of once-a-day
- C. One week before the allergy season begins, with four to six doses per day
- D. Just after manifestations begin, with a dose of twice-a-day
Correct Answer: D
Rationale: Cromolyn sodium (nasal crom) is a mast cell stabilizer that is commonly used to prevent symptoms of allergic rhinitis, such as sneezing, itching, and congestion. It works best when used before exposure to allergens. The most effective administration schedule for nasal crom is to start using it just after allergy symptoms begin, with a dose of twice-a-day. This helps to prevent the release of histamine and other inflammatory substances from mast cells, thereby reducing allergic symptoms. Using nasal crom in this way can help provide relief and improve the overall management of allergic rhinitis.
A patient receiving palliative care for end-stage liver cancer experiences severe nausea and vomiting despite antiemetic therapy. What should the palliative nurse consider when addressing the patient's symptoms?
- A. Increase the dosage of the current antiemetic medication.
- B. Switch to a different antiemetic medication with a different mechanism of action.
- C. Discontinue antiemetic therapy and explore non-pharmacological interventions.
- D. Administer intravenous fluids to alleviate dehydration associated with vomiting.
Correct Answer: B
Rationale: When a patient receiving palliative care for end-stage cancer experiences severe nausea and vomiting despite current antiemetic therapy, the palliative nurse should consider switching to a different antiemetic medication with a different mechanism of action. This approach is based on the concept of individual variability in response to medications, as well as the potential development of tolerance to a particular drug. Switching to a different antiemetic with a new mechanism of action can provide the patient with a fresh chance at better symptom control by targeting different receptors or pathways involved in nausea and vomiting. It is important to consult the healthcare team and consider the patient's overall condition and medication history before making any changes in the treatment plan.
