Correct Answer: D

Rationale: Population structure is a diagram that presents the distribution of a population based on age and sex. It is typically displayed in a pyramid-like style format, with the horizontal axis showing the age groups and the vertical axis showing the percentage or number of individuals in each age group, divided by sex. This helps to visualize how the population is distributed in terms of age and sex, providing important insights into demographic trends, such as age dependency ratio and potential future trends in population growth or decline. Age and sex are the key demographic variables used to construct a population structure diagram.

Correct Answer: C

Rationale: The nurse should prioritize removing the old dressing and applying a new dressing using sterile technique to minimize the risk of infection during a central venous catheter (CVC) dressing change. This is because the most critical step in preventing infection is maintaining a clean and sterile environment around the CVC insertion site. By using sterile technique, the nurse can reduce the introduction of microorganisms that could potentially lead to infection. Wearing sterile gloves and cleaning the insertion site with an alcohol-based antiseptic solution are important steps as well, but the key priority lies in applying the new dressing using sterile technique to prevent contamination and reduce the risk of infection.

Correct Answer: D

Rationale: The appropriate nursing diagnosis for this situation is "Ineffective coping" because the patients with hypertension who stop taking their medications despite feeling good may be using this behavior as a maladaptive coping mechanism. It suggests that they might not fully understand the importance of medication adherence or are struggling to accept their diagnosis. By not adhering to their prescribed treatment, they are putting themselves at risk for complications associated with uncontrolled hypertension. Therefore, the nursing diagnosis of "Ineffective coping" addresses the patients' inability to deal with their condition in a healthy manner, leading to noncompliance with their treatment regimen.

Correct Answer: A

Rationale: The correct instruction for using a metered-dose inhaler (MDI) with a spacer for a patient with COPD is to inhale slowly and deeply while pressing the canister. This technique helps ensure that the medication reaches the lungs effectively. Inhaling slowly and deeply allows the medication to be properly delivered to the airways, maximizing its effectiveness in treating the symptoms of COPD. This instruction helps the patient coordinate pressing the canister with their inhalation, which is crucial for proper medication delivery in COPD management.

Correct Answer: A

Rationale: An adequate contraction pattern during labor is characterized by regular contractions occurring at a frequency of three to 5 contractions in a 10-minute period, with resultant cervical dilatation. This pattern indicates efficient uterine activity that is helping to progress labor by dilating the cervix. In option A, the contractions are occurring at an appropriate frequency and are resulting in cervical dilatation, making it the correct choice for indicating an adequate contraction pattern.
