The healthcare provider is teaching a client with hypertension about lifestyle modifications. Which recommendation should the healthcare provider include?

  • A. Limit alcohol consumption to one drink per day.
  • B. Increase sodium intake to maintain blood pressure.
  • C. Exercise vigorously for at least 30 minutes daily.
  • D. Avoid high potassium foods like bananas.
Correct Answer: A

Rationale: Limiting alcohol intake is an essential lifestyle modification recommended for managing hypertension. Excessive alcohol consumption can raise blood pressure, so limiting it to one drink per day is beneficial in controlling hypertension. Alcohol moderation is a key part of a heart-healthy lifestyle for individuals with high blood pressure. Choice B is incorrect because increasing sodium intake can actually worsen hypertension by retaining water and increasing blood pressure. Choice C is incorrect because while exercise is important for overall health, moderate-intensity exercise is recommended for individuals with hypertension to avoid excessive strain on the heart. Choice D is incorrect because high potassium foods like bananas are actually beneficial for individuals with hypertension as they can help lower blood pressure.

A client is diagnosed with thrombophlebitis. The nurse should tell the client that which prescription is indicated?

  • A. Bed rest, with bathroom privileges only
  • B. Bed rest, keeping the affected extremity flat
  • C. Bed rest, with elevation of the affected extremity
  • D. Bed rest, with the affected extremity in a dependent position
Correct Answer: C

Rationale: The correct answer is C: Bed rest, with elevation of the affected extremity. Elevating the affected extremity is crucial in managing thrombophlebitis as it helps reduce swelling and promotes venous return. By elevating the affected extremity, the gravitational force assists in venous blood flow back to the heart, thereby reducing the risk of complications associated with thrombophlebitis. Choices A, B, and D are incorrect because they do not address the need for elevation, which is specifically beneficial in the management of thrombophlebitis.

A client diagnosed with thrombophlebitis 1 day ago suddenly complains of chest pain and shortness of breath. The LPN/LVN understands that a life-threatening complication of this condition is which?

  • A. Pneumonia
  • B. Pulmonary edema
  • C. Pulmonary embolism
  • D. Myocardial infarction
Correct Answer: C

Rationale: The correct answer is C, Pulmonary embolism. Pulmonary embolism is a critical complication of thrombophlebitis where a blood clot dislodges and travels to the lungs, obstructing blood flow. This obstruction can lead to chest pain, shortness of breath, and potentially fatal consequences, making it a life-threatening emergency that requires prompt intervention. Choices A, B, and D are incorrect because pneumonia, pulmonary edema, and myocardial infarction are not directly associated with thrombophlebitis and would not present with the sudden onset of chest pain and shortness of breath in this context.

Signs of tolerance include:

  • A. Needing higher doses for the same effect
  • B. Reduced side effects over time
  • C. Increased sensitivity to the drug
  • D. All of the above
Correct Answer: A

Rationale: Choice A is correct because tolerance is defined by needing more drug for the same effect due to body adaptation, per pharmacokinetic principles. Choice B is incorrect as reduced side effects may occur but aren't the definition. Choice C is wrong because sensitivity decreases, not increases. Choice D is incorrect since only A fits.

A client has a new prescription for verapamil. Which of the following beverages should the client avoid while taking this medication?

  • A. Orange juice
  • B. Coffee
  • C. Milk
  • D. Grapefruit juice
Correct Answer: D

Rationale: Grapefruit juice should be avoided while taking verapamil as it can increase drug levels and the risk of side effects. The interaction between grapefruit juice and verapamil can lead to higher concentrations of the medication in the bloodstream, potentially causing adverse effects. Orange juice, coffee, and milk do not have significant interactions with verapamil. Therefore, it is crucial for the client to avoid grapefruit juice to ensure the safe and effective use of verapamil.

A client with a history of angina pectoris reports chest pain after climbing stairs. What should be the nurse's first action?

  • A. Administer oxygen.
  • B. Administer nitroglycerin.
  • C. Sit the client down and rest.
  • D. Check the client's blood pressure.
Correct Answer: C

Rationale: The correct action for a client experiencing anginal pain, like chest pain after climbing stairs, is to sit the client down and have them rest. Resting reduces myocardial oxygen demand, which can help relieve anginal pain. Administering oxygen or nitroglycerin may be appropriate interventions after the client has been seated and rested. Checking the client's blood pressure is important but not the immediate priority when a client is experiencing anginal pain. Therefore, the first action should be to sit the client down and allow them to rest.
