Nursing Elites

1. Which of the following is the best guarantee that the patient’s priority needs are met?

• A. Checking with the relative of the patient
• B. Preparing a nursing care plan in collaboration with the patient
• C. Consulting with the physician
• D. Coordinating with other members of the team

Correct answer: B

Rationale: Preparing a nursing care plan in collaboration with the patient is the best guarantee that the patient's priority needs are met because it involves actively involving the patient in their own care. This approach ensures that the patient's preferences, concerns, and priorities are taken into account when planning their care. Checking with the relative of the patient, consulting with the physician, and coordinating with other team members are important aspects of patient care, but collaborating with the patient directly ensures a patient-centered approach that addresses their individual needs and preferences.

2. What happens to the density of a gas when its temperature increases at constant pressure?

• A. It increases.
• B. It decreases.
• C. It remains the same.
• D. Information insufficient

Correct answer: B

Rationale: As gas particles gain thermal energy with increasing temperature, they spread out, decreasing the density.

3. What is the main function of the endoplasmic reticulum (ER) in the cell?

• A. To synthesize and transport proteins and lipids
• B. To package and transport proteins
• C. To break down macromolecules
• D. To store genetic material

Correct answer: A

Rationale: Rationale: A) The endoplasmic reticulum (ER) is a network of membranes within the cell that plays a crucial role in protein and lipid synthesis. It consists of two types: rough ER, which is studded with ribosomes and involved in protein synthesis, and smooth ER, which is involved in lipid synthesis and detoxification. The ER also plays a role in transporting these synthesized proteins and lipids to other parts of the cell or outside the cell. B) While the ER is involved in packaging proteins, the main function is not solely to package and transport proteins. This function is more associated with the Golgi apparatus. C) Breaking down macromolecules is primarily the function of lysosomes, which are membrane-bound organelles containing enzymes for digestion. D) Storing genetic material is the function of the nucleus, which houses the cell's DNA. The ER is not involved in storing

4. What is the scientific term for the involuntary rhythmic contraction and relaxation of the heart muscle?

• A. Peristalsis
• B. Myogenesis
• C. Myocardial contractility
• D. Systole and diastole

Correct answer: D

Rationale: The correct answer is D: Systole and diastole. Systole refers to the phase of the heartbeat when the heart muscle contracts and pumps blood out, while diastole is the phase when the heart muscle relaxes and fills with blood. This rhythmic contraction and relaxation of the heart muscle is crucial for maintaining blood circulation throughout the body. Peristalsis (option A) is the involuntary constriction and relaxation of the muscles of the gastrointestinal tract that pushes contents forward. Myogenesis (option B) is the formation of muscle tissue. Myocardial contractility (option C) refers to the ability of the heart muscle to contract. Therefore, the most appropriate term for the described process is systole and diastole.

5. The lymphatic system works closely with which other body system to fight infections?

• A. Respiratory system
• B. Digestive system
• C. Immune system
• D. Nervous system

Correct answer: A

Rationale: The correct answer is the Respiratory system. The lymphatic system and the respiratory system work closely together to fight infections. The respiratory system helps to filter out pathogens and other harmful substances from the air we breathe, while the lymphatic system produces and transports white blood cells (lymphocytes) that play a key role in the immune response against infections. This collaboration helps the body to defend against respiratory infections and maintain overall health.

6. Which property of a wave remains constant when the wave enters a different medium?

• A. Frequency
• B. Wavelength
• C. Amplitude
• D. Speed

Correct answer: d

Rationale: The speed of a wave remains constant when it enters a different medium, provided the conditions are unchanged.
