When the findings of the study can be applied to all patients with MI under stress patients in the whole Philippines, it satisfies which of the following criteria in research?

Correct Answer: B

Rationale: Generalizability refers to the extent to which research findings and conclusions can be applied beyond the specific conditions of the study to a larger population or different settings. In this case, if the findings of a study on patients with myocardial infarction (MI) under stress can be applied to all such patients in the whole Philippines, it indicates that the study results are generalizable beyond the specific sample studied. Therefore, the criteria satisfied in this context is generalizability.

Correct Answer: B

Rationale: The patient who had a left total hip replacement surgery due to osteoarthritis needs to strictly follow the postoperative teaching of being shown how to gently irrigate the external auditory canal because this instruction is unrelated to a hip replacement surgery. The other options are not relevant to the surgery and patient's condition. Option A about airplane travel, Option C about dizziness, and Option D about hair washing are not appropriate instructions for a patient who had a hip replacement. It is important for healthcare providers to give accurate and relevant postoperative instructions to help the patient recover successfully.

Correct Answer: D

Rationale: In the situation described, where the client experienced a prolonged labor and instrumental delivery, there may be physical and emotional factors impacting breastfeeding success. A lactation consultant is a specialized healthcare provider who can assess the client's breastfeeding difficulties, offer individualized support, and provide guidance on techniques to overcome challenges such as latch issues, positioning problems, and milk supply concerns. Referring the client to a lactation consultant will help ensure that she receives expert assistance tailored to her specific needs, thereby increasing the likelihood of successful breastfeeding. This proactive approach focuses on addressing the root causes of breastfeeding difficulties and supporting the client in achieving her breastfeeding goals.

Correct Answer: D

Rationale: Nephrolithiasis refers to the formation of stones within the kidney or urinary tract. The most common types of kidney stones are either composed of calcium oxalate or calcium phosphate. When these stones form within the renal collecting system, they can lead to symptoms such as flank pain, hematuria, and urinary obstruction. Ureteropelvic junction (UPJ) obstruction and ureterovesical junction (UVJ) obstruction are specific types of blockages within the urinary system that can be caused by kidney stones but are not characteristic of the stone formation itself. Renal colic is the term used to describe the severe pain associated with the passage of a kidney stone through the ureter.

Correct Answer: C

Rationale: Hypokalemia (low levels of potassium) increases the risk of digoxin toxicity. This is because digoxin competes with potassium for binding sites on the sodium-potassium ATPase pump in the cell membrane. When potassium levels are low, there is an increased binding of digoxin to these pumps, leading to enhanced entry of calcium into the cells. This can result in an increased intracellular calcium concentration, leading to digoxin toxicity and potential cardiac arrhythmias. Therefore, monitoring and correcting potassium levels is crucial in patients prescribed digoxin to reduce the risk of toxicity.

Correct Answer: B

Rationale: Spondylosis is a condition characterized by degenerative changes in the intervertebral discs, leading to narrowing of the disc space and the formation of osteophytes (bone spurs). This degenerative process commonly occurs with aging and can cause symptoms such as neck or back pain, stiffness, and reduced range of motion. Spondylosis is a common finding on imaging studies like X-rays and MRI scans in individuals over the age of 50 and is a natural part of the aging process of the spine.

Correct Answer: C

Rationale: The hypothalamus is the link between the nervous system and the endocrine system. It plays a crucial role in maintaining homeostasis in the body by communicating with the pituitary gland, which is often referred to as the "master gland" of the endocrine system. The hypothalamus produces hormones that regulate the release of hormones from the pituitary gland, which then controls the functions of other endocrine glands throughout the body. This connection allows the nervous system to influence and coordinate various hormonal responses in the body, helping to regulate processes such as metabolism, growth, stress responses, and reproduction.

Correct Answer: C

Rationale: When assessing and managing distress in a patient with advanced dementia who is no longer able to communicate verbally, the palliative nurse should consider exploring non-verbal cues and behaviors to identify the underlying causes of distress. Since the patient cannot communicate through words, it is essential to pay close attention to their non-verbal cues such as facial expressions, body language, and changes in behavior. Distress in dementia patients can be caused by a variety of factors including physical discomfort, unmet needs, environmental stressors, emotional distress, or even medication side effects. By carefully observing and interpreting non-verbal cues, the nurse can gain insight into what might be causing the patient's distress and tailor interventions accordingly. Simply focusing on physical comfort measures may not address the root cause of the distress, and administering sedative medications without understanding the underlying cause is not considered best practice in palliative care for dementia patients.

Correct Answer: A

Rationale: The nurse should prioritize using sterile technique during the tracheostomy tube change to ensure patient safety. Tracheostomy procedures involve a direct entry into the airway, making it crucial to prevent infection and reduce the risk of complications. Sterile technique, including proper hand hygiene, wearing sterile gloves, and using sterile equipment, helps minimize the introduction of pathogens into the patient's airway, reducing the risk of infection. By maintaining a sterile field, the nurse can protect the patient from potential harm and promote a successful outcome of the tracheostomy tube change.
