The physician orders cromolyn sodium (nasal crom) for the client. The nurse instructs the client that the most effective administration schedule is ________.

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.

Correct Answer: D

Rationale: Nurse Noli should not advise patients to eat more saturated fats. Saturated fats are known to increase cholesterol levels and can lead to heart disease and other health issues. It is recommended to limit the intake of saturated fats in the diet. Therefore, advising patients to eat more saturated fats goes against the goal of promoting heart-healthy habits. Instead, Nurse Noli should focus on encouraging patients to cut down on salt intake, consume more fruits and vegetables, and eat regular meals to maintain a balanced and healthy diet.

Correct Answer: C

Rationale: The indicators listed indicate measures that Nurse Cirila can take to maintain a safe environment for her pediatric patients. However, assessing the competencies of staff before delegating a task is more related to ensuring effective delegation and appropriate task assignment rather than directly ensuring a safe environment for patients. While it is important to delegate tasks to qualified staff, this specific action does not directly contribute to maintaining a safe environment in the same manner as the other indicators listed (proper waste disposal, infection control, emergency protocols).

Correct Answer: D

Rationale: In a longitudinal study design, the nurse researcher collects data at multiple points over an extended period of time. This design allows for the examination of changes or trends over time within the same group of participants. It helps in understanding the long-term effects and relationships between variables by tracking the same individuals over a prolonged duration. This design is particularly useful in studying developmental patterns, chronic diseases, or long-term treatment outcomes.

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: Von Willebrand disease is a hereditary bleeding disorder that results from a deficiency or dysfunction of von Willebrand factor (vWF), a protein that plays a key role in platelet adhesion and the initiation of primary hemostasis. The clinical manifestations of von Willebrand disease include recurrent mucocutaneous bleeding, such as nosebleeds, easy bruising, and gum bleeding. Laboratory findings typically show a prolonged bleeding time due to impaired platelet function, while platelet count, PT (prothrombin time), and aPTT (activated partial thromboplastin time) are usually normal. This distinguishes von Willebrand disease from other bleeding disorders such as hemophilia A (Factor VIII deficiency), which would show abnormal PT and aPTT due to deficiencies in specific clotting factors. Thrombocytopenia, on the other hand, would be characterized by a low platelet count

Correct Answer: A

Rationale: The appropriate approach of the nurse in this situation would be to talk about the reality of death with the father. It is important to provide appropriate and compassionate communication, acknowledging the father's grief while also gently guiding him towards accepting the reality of the situation. By discussing the reality of death and offering support, the nurse can help the father start the grieving process and eventually come to terms with the loss of his son. It is important to provide emotional support and guidance in a sensitive and respectful manner during such a difficult time.

Correct Answer: A

Rationale: The nurse should prioritize ensuring proper zeroing and calibration of the ICP monitoring system to ensure procedural accuracy and reliability of the measurements obtained. Proper zeroing involves setting the transducer at the level of the patient's external auditory meatus (ear), which serves as a reference point for accurate ICP readings. Calibration is necessary to establish accurate pressure measurements. Incorrect zeroing or calibration can lead to inaccurate ICP readings, which can impact clinical decision-making for patients with traumatic brain injury. Positioning the patient in a high-Fowler's position, administering prophylactic antibiotics, or placing the ICP monitor in the subarachnoid space via lumbar puncture are not directly related to ensuring the accuracy of the ICP monitoring procedure.

Correct Answer: A

Rationale: Battery refers to the intentional and offensive physical contact with another person without their consent, resulting in harm or injury. In this scenario, the victim clearly expressed their unwillingness to be touched or helped by saying, "Don't touch me!" multiple times. By ignoring the victim's refusal and physically forcing them into the ambulance, the EMT is committing battery even though they may have had good intentions to provide assistance. It is important for medical professionals, including EMTs, to always respect a person's right to refuse medical treatment or assistance, even in emergency situations.
