Nursing Elites

1. Which of the following are key parameters that produce blood pressure? (Select ONE that does not apply)

• A. Heart rate
• B. Stroke volume
• C. Peripheral resistance
• D. Neuroendocrine hormones

Correct answer: D

Rationale: Heart rate, stroke volume, and peripheral resistance are indeed key parameters that directly influence blood pressure. Heart rate refers to the number of times the heart beats per minute, affecting how much blood is pumped. Stroke volume is the amount of blood pumped by the heart in one contraction. Peripheral resistance is the resistance of the arteries to blood flow, impacting the pressure needed to push blood through. Neuroendocrine hormones, while they can indirectly influence blood pressure regulation by affecting factors like blood volume and vascular tone, are not direct final parameters that produce blood pressure.

2. The nurse is teaching a client about the administration of a subcutaneous injection. Which site is most appropriate for this type of injection?

• A. Deltoid muscle
• B. Dorsogluteal muscle
• C. Ventrogluteal muscle
• D. Abdomen

Correct answer: D

Rationale: The abdomen is a common site for subcutaneous injections due to its accessibility and ample subcutaneous tissue. Subcutaneous injections are typically given in areas with a layer of fat between the skin and muscle, such as the abdomen, to allow for slow and consistent absorption of the medication. The deltoid muscle is more appropriate for intramuscular injections, not subcutaneous. The dorsogluteal muscle and ventrogluteal muscle are also more suited for intramuscular injections, not subcutaneous.

3. What is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space?

• A. Filtration
• B. Diffusion
• C. Osmosis
• D. Active transport

Correct answer: C

Rationale: The correct answer is C: Osmosis. Osmosis is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space to maintain cellular balance. In osmosis, water moves across a semi-permeable membrane from an area of low solute concentration (hypotonic) to an area of high solute concentration (hypertonic). This process helps regulate the water content inside cells. Choices A, B, and D are incorrect. Filtration involves the movement of solutes and solvents through a membrane due to a pressure difference, diffusion is the movement of solutes from an area of high concentration to low concentration, and active transport requires energy to move substances against their concentration gradient.

4. What is the most important information the nurse should teach a diabetic client about foot care?

• A. Inspect feet daily
• B. Wear cotton socks
• C. Use lukewarm water to wash feet
• D. Cut nails straight across

Correct answer: A

Rationale: The correct answer is to inspect feet daily. For diabetic clients, daily foot inspection is crucial in preventing complications like infections and ulcers. By checking their feet regularly, clients can identify any issues early and seek appropriate medical care. The other choices are important aspects of foot care for diabetic clients but not as critical as daily foot inspections. Wearing cotton socks helps in moisture control, using lukewarm water to wash feet helps prevent skin damage, and cutting nails straight across prevents ingrown nails. However, daily foot inspection is the most vital as it allows for early detection of any potential problems, which is key in diabetic foot care.

5. The nurse is caring for a client postoperatively following a thyroidectomy. Which assessment finding should be reported to the healthcare provider immediately?

• A. Hoarseness of the voice.
• B. Slight swelling at the incision site.
• C. Tingling around the mouth.
• D. Mild fever.

Correct answer: C

Rationale: Tingling around the mouth should be reported to the healthcare provider immediately as it may indicate hypocalcemia, a potential complication after thyroidectomy. Hoarseness of the voice is common postoperatively due to surgical manipulation, slight swelling at the incision site is a normal response, and a mild fever can be expected after surgery. However, tingling around the mouth suggests a potential calcium imbalance, which requires prompt attention to prevent serious complications.
