A patient presents with a Colles' fracture. What is the characteristic deformity associated with this type of fracture?
- A. Dorsal displacement of the distal fragment
- B. Ventral displacement of the distal fragment
- C. Lateral displacement of the distal fragment
- D. Medial displacement of the distal fragment
Correct Answer: A
Rationale: Colles' fracture is a type of distal radius fracture characterized by a break of the radius bone in the forearm close to the wrist. In a Colles' fracture, the distal fragment of the fractured radius bone gets displaced dorsally, meaning it shifts upwards towards the back of the hand, creating a characteristic "dinner fork" deformity when viewed from the side. This dorsal displacement results in a visible bump on the back of the wrist and a noticeable deformity when compared to the uninjured side.

Which endocrine disorder is most likely responsible for these symptoms?
- A. Hashimoto's thyroiditis
- B. Graves' disease
- C. Diabetes mellitus
- D. Thyroid nodules
Correct Answer: B
Rationale: The symptoms described—tachycardia, weight loss, and tremors—are consistent with hyperthyroidism. Graves' disease is the most common cause of hyperthyroidism and is an autoimmune disorder in which the thyroid gland is overactive. This condition can lead to an increased production of thyroid hormones, resulting in symptoms such as rapid heartbeat (tachycardia), unintended weight loss, and tremors. In contrast, Hashimoto's thyroiditis is an autoimmune disorder that causes hypothyroidism, leading to symptoms like fatigue, weight gain, and cold intolerance. Diabetes mellitus is a metabolic disorder characterized by high blood sugar levels, which typically presents with symptoms such as increased thirst, frequent urination, and fatigue. Thyroid nodules are growths within the thyroid gland that can sometimes be associated with overactive (hyperthyroidism) or underactive (hypothyroidism) thyroid function, but they do not
The MOST significant contributory factor to the development of lung cancer is ________.
- A. being a cigarette smoker
- B. belonging to the male sex
- C. Being extremely obese
- D. age over 4 0years
Correct Answer: A
Rationale: The most significant contributory factor to the development of lung cancer is being a cigarette smoker. Cigarette smoking is directly linked to approximately 85% of lung cancer cases. The harmful substances in tobacco smoke, such as carcinogens, damage the cells in the lungs, leading to the development of cancer over time. Smokers are at a significantly higher risk of developing lung cancer compared to non-smokers. Therefore, being a cigarette smoker is the primary and most influential risk factor for developing lung cancer.
Baby Sharon was placed on phototherapy. What precaution should Nurses Juvy observe?
- A. Put sunglasses on the newborn to protect his/her eyes.
- B. Be certain that the newborn's intake is adequate.
- C. Assess the newborn for symptoms of headache.
- D. Keep the newborn wrapped to prevent sunburn.
Correct Answer: A
Rationale: When a baby is placed on phototherapy, especially for treating jaundice, it is crucial for the nurses to put sunglasses on the newborn to protect their eyes. Phototherapy involves exposing the baby's skin to certain types of light to help break down the bilirubin causing the jaundice. However, this light can be harmful to the baby's sensitive eyes, potentially leading to eye damage or other eye-related issues if not protected adequately. Therefore, placing sunglasses on the newborn is a necessary precaution to ensure the safety and well-being of the baby's eyes during the treatment.
A woman in active labor is diagnosed with a prolapsed umbilical cord. What is the priority nursing action?
- A. Elevate the mother's hips to relieve pressure on the cord.
- B. Prepare for immediate cesarean section.
- C. Administer intravenous fluids rapidly.
- D. Perform a vaginal examination to assess cervical dilation.
Correct Answer: B
Rationale: A prolapsed umbilical cord is a medical emergency during labor because it can cause compression of the umbilical cord, leading to decreased oxygen supply to the fetus. The priority nursing action in this situation is to prepare for an immediate cesarean section. This is necessary to quickly deliver the baby and relieve pressure on the cord, preventing potential fetal distress or death. Elevating the mother's hips may help reduce pressure on the cord temporarily, but it is not the definitive treatment for a prolapsed cord. Administering intravenous fluids rapidly may be necessary, but it is not the priority intervention when the fetus is at risk due to a prolapsed cord. Performing a vaginal examination to assess cervical dilation is contraindicated in the presence of a prolapsed umbilical cord as it can further compress the cord and worsen the situation.
In the ethical principle of beneficence, which is the BASIS of every nursing action in all work settings?
- A. Treating all patients selectively.
- B. Informing patients of hospital bills.
- C. Respecting refusal of treatment.
- D. Doing good at all times.
Correct Answer: D
Rationale: The ethical principle of beneficence, which is the basis of every nursing action in all work settings, emphasizes the importance of doing good at all times for the benefit of the patient. Nurses are expected to act in the best interest of their patients and strive to promote their well-being and welfare. This principle guides nurses to provide care that is compassionate, effective, and in line with the patient's needs and preferences. By prioritizing the good of the patient in all actions and decisions, nurses uphold the principle of beneficence and demonstrate their commitment to promoting positive outcomes for those under their care.
