Which of the following interventions is most appropriate for a patient with a tension pneumothorax?

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.

Correct Answer: C

Rationale: The symptoms described, including progressive weakness, muscle atrophy, fasciculations, dysphagia, and dysarthria primarily involving the upper and lower extremities, are classic features of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease. ALS is a progressive neurodegenerative disorder that affects the motor neurons in the brain and spinal cord, leading to muscle weakness and atrophy. As the disease progresses, patients may develop difficulty swallowing (dysphagia) and speaking (dysarthria). In contrast, Parkinson's disease primarily involves movement-related symptoms such as tremors, muscle stiffness, and slow movements. Guillain-Barré syndrome (GBS) is an acute inflammatory demyelinating polyneuropathy that typically presents with ascending weakness and sensory abnormalities, often preceded by an infection. Myasthenia gravis is characterized by muscle weakness exacerbated by

Correct Answer: A

Rationale: The liver is responsible for secreting bile, which aids in the emulsification and digestion of fats. Bile is produced by the liver and is stored and concentrated in the gallbladder before being released into the small intestine to help with the breakdown of fats during the digestion process. The gallbladder functions as a storage organ for bile produced by the liver. The pancreas secretes digestive enzymes and bicarbonate to aid in the digestion process, while the spleen is mainly involved in immune function and blood storage.

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: B

Rationale: A severe headache is a classic sign of a hemorrhagic stroke. Hemorrhagic stroke occurs when a blood vessel in the brain ruptures and causes bleeding. This bleeding can lead to increased pressure within the skull, resulting in a sudden and severe headache. Other symptoms of a hemorrhagic stroke may include nausea, vomiting, sudden weakness or numbness on one side of the body, difficulty speaking or understanding speech, and loss of coordination. It is important to seek immediate medical attention if someone is experiencing symptoms of a stroke, including a severe headache, as prompt treatment is crucial in minimizing damage and improving outcomes.

Correct Answer: D

Rationale: When performing an intramuscular (IM) injection, the nurse should insert the needle at a 90-degree angle into the muscle. This angle helps ensure proper and deep penetration into the muscle tissue for effective administration of the medication. It also helps prevent leakage or tissue damage at the injection site. Additionally, inserting the needle at a 90-degree angle facilitates accurate delivery of the medication into the muscle where it can be absorbed properly. Therefore, selecting the correct angle for inserting the needle is critical in ensuring the success and effectiveness of the IM injection.

Correct Answer: D

Rationale: When someone is bitten by a dog, the most important first aid step is to wash the wound thoroughly with running water. This helps to remove any dirt or bacteria from the wound, reducing the risk of infection. Washing the wound with garlic (choice A) is not recommended as it can irritate the skin and may not effectively clean the wound. Feeding the dog (choice B) is not relevant to treating the bite wound. Bleeding the bitten area (choice C) is also not necessary and can actually increase the risk of infection. Therefore, the best advice the nurse should give in case of a dog bite is to wash the wound thoroughly with running water.

Correct Answer: A

Rationale: The presentation of well-demarcated, hypopigmented macules with fine scaling on the trunk and proximal extremities is classic for tinea versicolor. Tinea versicolor is a common superficial fungal infection caused by Malassezia spp., which leads to hypo- or hyperpigmented patches on the skin. The condition often occurs in individuals with increased sebum production due to factors such as hot and humid climates, sweating, and oily skin. History of sun exposure and outdoor activities is also commonly reported by patients with tinea versicolor. Treatment usually involves antifungal medications applied topically or taken orally to eliminate the fungus. Differentiating tinea versicolor from other skin conditions, such as vitiligo, pityriasis rosea, or seborrheic keratosis, is important for appropriate management.

Correct Answer: A

Rationale: Pressure injuries on the heels are a concern as they can develop quickly and lead to serious complications, especially in surgical patients who are immobile for extended periods. Applying pressure-relieving devices, such as heel protectors or foam dressings, can help alleviate the pressure on the affected areas and prevent further damage. These devices are designed to distribute pressure evenly and reduce the risk of pressure injuries. It is important for the nurse to address the issue promptly to prevent additional harm to the patient's skin integrity.
